  98.           The text in this  part contains a set of Message  Handling System
  99.           (MHS) Implementation  Agreements intended to serve in  lieu of an
  100.           International Standardized Profile (ISP) for  MHS.  It is the aim
  101.           of the OIW X.400 SIG to  pursue alignment of this  part  with the
  102.           developing ISP.   When the ISP  is complete, this   part will  be
  103.           revised to  refer to  the ISP, and  to only  highlight additional
  104.           practices and North American regional requirements.

  737.           0   Introduction
  738.  
  739.           This  is   an   Implementation   Agreement   developed   by   the
  740.           Implementors'  Workshop sponsored by the U. S. National Institute
  741.           of  Standards and  Technology to promote  the useful  exchange of
  742.           data between  devices  manufactured by  different  vendors.  This
  743.           Agreement is based on, and  employs protocols developed in accord
  744.           with, the OSI Reference Model. It  provides detailed guidance for
  745.           the implementor and eliminates ambiguities in interpretations.
  746.  
  747.           This  is an Implementation Agreement for Message Handling Systems
  748.           (MHS) based on the CCITT  X.400 (1988) series of Recommendations,
  749.           the  similar  (but   not  identical)  ISO  MOTIS   standard,  and
  750.           Recommendations F.435  and X.435  (1991) (see  References). These
  751.           Recommendations  and  Standards  are  referred  to  as  the  base
  752.           standards. The term "MHS" is used  to refer to both sources where
  753.           a  distinction is unnecessary.  Similarly, "1984" and  "1988" are
  754.           often  used to distinguish between the  CCITT X.400 (1984) series
  755.           of Recommendations and the later sources.
  756.  
  757.           This  Implementation  Agreement  seeks   to  establish  a  common
  758.           specification which is conformant with  both CCITT and ISO with a
  759.           view to:
  760.  
  761.                a)  Preventing  a proliferation of incompatible  communities
  762.                of MHS systems which are isolated for protocol reasons;
  763.  
  764.                b)   Achieving interworking with  implementations conforming
  765.                to the OIW  Stable Implementation Agreements for  CCITT 1984
  766.                X.400-based Message Handling Systems; and,
  767.  
  768.                c)    Facilitating integration  of other  OSI-based services
  769.                (e.g., Directory) within a single real system.
  770.  
  771.           This Implementation Agreement is designed to encourage upgrade of
  772.           existing 1984-based systems as follows:
  773.  
  774.                a)  To  add 1988 functionality  (Message Store, Remote  User
  775.                Agent, etc.); 
  776.  
  777.                b)   To provide  additional functionality above  the minimal
  778.                conformant 1988  MHS defined in the December 1989 version of
  779.                the OIW Implementation  Agreements.  These 1988  aspects are
  780.                described   in   this   Agreement   as  either   incremental
  781.                enhancements or new functional groups.
  782.  
  783.           However,  it is  considered that  the  OIW Stable  Implementation
  784.           Agreements  for CCITT 1984  X.400-based Message  Handling Systems
  785.           (part 7) should not be withdrawn at this stage. It is anticipated

  802.           that  X.400 (1984)  implementations will  continue  to provide  a
  803.           viable  alternative  for  applications that  do  not  require the
  804.           additional 1988 functionality for some time.
  805.

  807.           1   Scope
  808.  
  809.           This Agreement specifies the requirements for MHS implementations
  810.           based on the 1988 MHS standards.
  811.  
  812.           This  Agreement  applies equally  to  Private Management  Domains
  813.           (PRMDs)  and  Administration  Management  Domains  (ADMDs).  Four
  814.           boundary interfaces are specified, as illustrated in figure 1:
  815.  
  816.                a)  Management Domain (MD) to MD;
  817.  
  818.                b)  Message Transfer Agent (MTA) to MTA within a domain;
  819.  
  820.                c)   MTA to remote  Message Store (MS)  or User  Agent (UA);
  821.                and,
  822.  
  823.                d)  MS to Remote UA.
  824.  
  825.           MHS protocols other than the Message Transfer Protocol (P1),  the
  826.           Message Transfer System  Access Protocol (P3),  the Interpersonal
  827.           Messaging  Protocol (P2), and  the Message Store  Access Protocol
  828.           (P7) are beyond the scope  of this Agreement. Issues arising from
  829.           the  use  of  other  protocols  are outside  the  scope  of  this
  830.           document.  This Agreement describes the services provided at each
  831.           interface shown in figure 1.
  832.  
  833.           MHS implementations may be configured  as any single or  multiple
  834.           occurrence or  combination of MTA,  MS and UA, as  illustrated in
  835.           figure 1. It is not intended to restrict the types of system that
  836.           may be configured for conformance  to this Agreement (although it
  837.           is equally recognized  that not  all configuration  types may  be
  838.           commercially viable).

  935.  
  936.           The  1988  MHS  standards  cover  a wide  and  diverse  range  of
  937.           functional areas,  not all  of which would  be relevant  to every
  938.           implementation. In order to achieve a more  precise definition of
  939.           conformance requirements according to the functionality supported
  940.           by  an  implementation,  and  additionally  to facilitate  future
  941.           enhancement  of  this  initial   specification,  the  concept  of
  942.           Functional Groups has  been introduced. Conformance  requirements
  943.           for support of Functional Groups by particular configurations are
  944.           specified in clause 17.
  945.  
  946.           In the context of these agreements, the term "Support" means that
  947.           the  service provider makes  the element of  service (and related
  948.           elements of protocol) available to the service user. The  service
  949.           user provides adequate access  to invoke the elements of  service
  950.           and/or  makes information  associated  with  the service  element
  951.           available.  Additionally, for  "Not Defined" or  "Not Applicable"
  952.           elements, the  service  provider  is  not required  to  make  the
  953.           element  available  to  the service  user.  However,  the service
  954.           provider  should not regard  the occurrence of  the corresponding
  955.           protocol elements  as an error  and should relay  those elements.
  956.           Naturally,  protocol  elements  marked critical  for  submission,
  957.           transfer,  or delivery  must be processed  according to  the base
  958.           standards.
  959.

  1095.           This  version  of  the  Implementation  Agreements  for   Message
  1096.           Handling Systems (MHS)  is under development. It is  based on the
  1097.           CCITT X.400 (1988) Recommendations and ISO MOTIS (10021, parts 1-
  1098.           7) standards,  as amended by the MHS  Implementors Guide, version
  1099.           6.
  1100.  
  1101.           The  initial version  of these  Stable Implementation  Agreements
  1102.           included  an Agreement which  specified a minimal  1988-based MHS
  1103.           implementation and  support for  Message Stores  and Remote  User
  1104.           Agents,  and   which  addresses   interworking  with   1984-based
  1105.           implementations. This version of the  Agreement specifies support
  1106.           for several  additional 1988  features.   The remaining  features
  1107.           specified  in the  1988 standards will  be covered  in subsequent
  1108.           versions of this Agreement. 
  1109.  
  1110.           This  initial version  has not  yet been  aligned with  other MHS
  1111.           profiles,  so  changes  may  be  necessary  in  the   future  for
  1112.           international  harmonization,  e.g.,  support  for  international
  1113.           character repertoires and conversion.

  1140.           5.1    Introduction
  1141.  
  1142.           This clause specifies  the requirements for a  minimal 1988-based
  1143.           MTS implementation (i.e.,  MTA) which is capable  of interworking
  1144.           with 1984-based  MTAs. The  "base" MT  Service specified  in this
  1145.           clause does not include:
  1146.  
  1147.                a)  Message Store (see clause 6);
  1148.  
  1149.                b)  Remote UA (see clause 7);
  1150.  
  1151.                c)  Distribution Lists (see clause 8.3);
  1152.  
  1153.                d)  Use of Directory Services (see clause 8.4);
  1154.  
  1155.                e)  Security (see clause 10);
  1156.  
  1157.                f)    Interworking   with  Physical   Delivery  systems   or
  1158.                Specialized Access (see clause 11); and,
  1159.  
  1160.                g)  Conversion of body parts (see clause 13.6.2).
  1161.  
  1162.           Such  a   minimal  1988-based   MTA  will   have  the   following
  1163.           capabilities in  order to  achieve  interworking with  1984-based
  1164.           MTAs and to facilitate migration to full 1988 operation:
  1165.  
  1166.                a)  It will be protocol-conformant to 1988 P1;
  1167.  
  1168.                b)  It  will downgrade 1988 P1  to 1984 P1 when  relaying to
  1169.                1984-based MTAs,  as  specified in  Annex  B of  X.419  (see
  1170.                clause 5.5);
  1171.  
  1172.                c)   It  will support  both "normal"  mode and  "X.410-1984"
  1173.                ("passthrough")  mode protocol stacks  (i.e., as required by
  1174.                ISO and CCITT respectively); and,
  1175.  
  1176.                d)  A  conforming implementation shall obey  the criticality
  1177.                mechanism defined  in  the  base  standards.  The  following
  1178.                abstract operations are made critical for delivery for these
  1179.                Implementation Agreements: message  token, content integrity
  1180.                check, and content confidentiality algorithm Id.

  1199.  
  1200.           This clause specifies the requirements for support of MT Elements
  1201.           of Service by an MTA conforming to the MT Kernel Functional Group
  1202.           of this Agreement. Table 1 specifies the support for the basic MT
  1203.           Kernel elements of service and  table 2 specifies the support for
  1204.           the optional MT Kernel elements of service.
  1205.  
  1206.           The classification scheme for  support of Elements of  Service is
  1207.           as follows:
  1208.  
  1209.                Mandatory (M): the  Element of Service must be supported and
  1210.                made available to the service user;
  1211.  
  1212.                Optional (O):  the Element of Service may  be supported, but
  1213.                is not required for conformance to this Agreement;
  1214.  
  1215.                Out  of Scope  (I): the  Element of  Service is  outside the
  1216.                scope of these Implementation Agreements;
  1217.  
  1218.                Not Applicable (-): the Element of Service is not applicable
  1219.                in  the particular context  according to the  base standard;
  1220.                and,
  1221.  
  1222.                To Be  Determined (*):  the support  classification for  the
  1223.                Element of Service has yet to be determined.
  1224.  
  1225.           The requirements  for  support  of  MT Elements  of  Service  for
  1226.           origination  and  reception  and (where  relevant)  relaying  are
  1227.           distinguished. Elements of Service which  are new in the 1988 MHS
  1228.           standards are indicated as (1988).
  1229.  
  1230.           An MTA must  support those  Basic MT Elements  of Service and  MT
  1231.           Optional User Facilities defined in section 19 of X.400 (1988) as
  1232.           listed and qualified in tables 1 and 2.
  1233.  
  1234.           Specification of dynamic  behavior in these agreements  will only
  1235.           be   included  in  those  cases  where  there  is  an  identified

  1272.                restrictions  by  a  profile  on  the  dynamic   conformance
  1273.                requirements of a  base standard are exceptions,  and should
  1274.                only apply to transmission. Restrictions should not apply to

  1276.                possible to  ensure that such  options are not  initiated or
  1277.                transmitted.   However,  it  is   still  possible   that  an
  1278.                implementation  may  receive  an Excluded  element  from  an
  1279.                implementation which does not conform to the same profile.

  1619.                not support Internal  Trace Information per clause  7.3.2 of
  1620.                part 7, the following description is  not applicable. When a
  1621.                1988-based  MTA supports interworking  with a 1984-based MTA
  1622.                that  generates Internal  Trace  Information  as per  clause
  1623.                7.3.3  of part 7, the  1988-based MTA must support reception
  1624.                of the Internal Trace Information by converting the Internal
  1625.                Trace Information from the form in clause 7.3.2 of part 7 to
  1626.                the  form  specified in  1988  X.411, as  per  the following
  1627.                description. When  the 1988-based MTA  sends to a  1984 MTA,
  1628.                the 1988-based  MTA must  apply the  conversion to  1984, as
  1629.                described below.  The Stable  NBS Implementation  Agreements
  1630.                X.400 (1984) definition for MTA's Internal Trace Information
  1631.                is  different   from  the   X.400  (1988)   MTA  definition.
  1632.                Consequently, a  X.400 (1988)  MTA operating  in an MD  with
  1633.                other  MTAs of  1984 vintage,  must map  the Internal  Trace
  1634.                Information to and/or from the 1984 format.

  1639.  
  1640.           To avoid potential looping within a MD composed of 1984  and 1988
  1641.           vintage MTAs, MD  administrators are strongly advised to name all
  1642.           MTAs (1984  and 1988  vintages) using  only the  Printable String
  1643.           characters. In X.400  (1988) the MTA-Name is defined  to be named

  1763.           This  clause  specifies  Agreements  for  implementation  of  the
  1764.           Message Store (MS)  Functional Group. The  MS is responsible  for
  1765.           accepting delivery  of messages on  behalf of a  single end-user,
  1766.           and retaining  the messages  until the end-user's  UA is  able to
  1767.           retrieve  them.  Message   submission  and  some   administration

  1805.           The Agreements in this clause  specify the Message Store's use of
  1806.           the retrieval, delivery, and  administration services. Agreements
  1807.           on submission services are specified in clause 7, which describes
  1808.           support for the Remote UA.
  1809.  
  1810.           The  goal of  the  Agreements in  this  clause is  to define  the
  1811.           minimal set  of features  which are necessary  to provide  useful
  1812.           Message Store  services,  independent of  the MTA  implementation

  1818.           The scope of  the Agreements in this clause is depicted in figure
  1819.           5,  and is  confined to  the services  and protocols  between the
  1820.           boundaries shown (marked with asterisks). Requirements for the UA
  1821.           and MTA  are addressed only  to the extent  that they  affect the
  1822.           Message Store and Remote User  Agent services and protocols. This
  1823.           reflects the additional services required at the UA to support MS
  1824.           access and at the MTA to support a remote MS.

  1895.  
  1896.           The Basic  MS  is intended  to support  the use  of the  MS as  a

  1898.           entity)  for receiving,  storing,  and  forwarding  messages  and
  1899.           reports. The  Basic MS  is not required  to support  any content-
  1900.           specific attributes.
  1901.  
  1902.           The Enhanced MS  supports a larger  number of general  attributes
  1903.           and  is  suited   to  MSs  that  also   support  content-specific
  1904.           attritbutes.
  1905.  
  1906.           Additionally,  support  for  security  attributes  is defined  in

  2145.           8.2    ORAddress attribute list equivalence rules
  2146.  
  2147.           Two ORAddresses are  equivalent if each contains the  same set of
  2148.           attributes and each attribute compares in type and value.
  2149.  
  2150.           The following equivalence  rules apply when comparing  a provided
  2151.           ORAddress with a collection of known ORAddresses. For example, in
  2152.           order to perform delivery  of a message  to a recipient, the  MTA
  2153.           must unambiguously match  the ORAddress contained in  the message
  2154.           with the  known ORAddresses. See X.402 (1988),  section 18.4, for
  2155.           the  base  standard  attribute equivalence  rules.  The following
  2156.           additional rules must also be  applied by the delivering (or non-
  2157.           delivering) MTA:
  2158.  
  2159.                a)     If   the  provided   ORAddress   is  an   unambiguous
  2160.                underspecification of a known ORAddress, the ORAddresses are
  2161.                equivalent. For example,  if the initials were  omitted, the
  2162.                ORAddress  would  still be  equivalent.  Under-specification
  2163.                means  that  some attributes  that  are not  present  in the
  2164.                provided  ORAddress are  present in  the known  ORAddresses.
  2165.                Under-specification  does  not  mean  partial  value  (e.g.,
  2166.                substring) equivalence when  the same set of  attributes are
  2167.                present in the ORAddresses.
  2168.  
  2169.                b)   Over-specified  ORAddresses are  not  equivalent. Over-
  2170.                specification  means that more attributes are present in the
  2171.                provided   ORAddress  than   are   present   in  the   known
  2172.

  2189.                for these purposes.
  2190.  
  2191.                c)  An  ADMD or PRMD name that is all numeric but encoded as
  2192.                Printable String is considered to be equivalent  to the same
  2193.                ADMD  or  PRMD  name, respectively,  with  the  same numeric
  2194.                values encoded as Numeric String.
  2195.  
  2196.                d)  An extension  attribute encoded as Teletex  String shall
  2197.                be  compared  with  the  corresponding  standard   attribute
  2198.                encoded as Printable  String if that extension  attribute is
  2199.                not  present in  both ORAddresses.   Matching  rules  are as
  2200.                specified in clause 18.4 of X.402 (1988) (as modified in the
  2201.                MHS  Implementors' Guide) except  that only  teletex graphic
  2202.                characters from  repertoire no. 102 need to  be compared for
  2203.                Printable String equivalence (i.e., the presence of  graphic
  2204.                characters  from other  repertoires  can  be  treated  as  a

  2276.  
  2277.  
  2278.           8.4.1   Introduction
  2279.  
  2280.           The MHS standards recognize the need of MHS users for a number of
  2281.           directory  service  elements.  Directory  service  elements   are
  2282.           intended  to  assist users,  their  UAs,  and  MTAs in  obtaining
  2283.           information for use  in submission, delivery, and the transfer of
  2284.           messages.
  2285.  
  2286.                NOTE - The  MTS may also use the  directory service elements
  2287.                to  obtain  information,  for example,  to  be  used  in the
  2288.                routing  of  messages.  This  application  of the  directory
  2289.                service  is  not  defined  by  the  base  standards  and  is
  2290.                therefore not addressed by this Agreement.

  2295.           Two  MHS functional  entities, the  UA  and MTA,  may access  the
  2296.           Directory  service  using  the Directory  User  Agent  (DUA). The
  2297.           interface between the UA and DUA, or MTA and DUA is local and not
  2298.           defined. The  interaction between  the DUA  and Directory  System
  2299.           Agent (DSA) is  specified in part 11. A collocated DUA and DSA is
  2300.           also permitted.

  2324.  
  2325.                a)  UA Specific Functionality:
  2326.  
  2327.                     1)  Verify the existence of a Directory Name;
  2328.  
  2329.                     2)     Given  a  partial   name,  return   a  list   of
  2330.                     possibilities;
  2331.  
  2332.                     3)    Search  the Directory  for  entries  containing a
  2333.                     specified  attribute  type  and  value  and return  the
  2334.                     Distinguished Names of the matching entries;

  2389.           8.4.4   Naming and attributes
  2390.  
  2391.           Since user-friendliness is  of primary importance in  a messaging
  2392.           system, the  naming conventions  used in  building the  Directory
  2393.           Information Tree (DIT) will impact the ability of a  user to make
  2394.           intelligent guesses for Directory Names.
  2395.  
  2396.           It is recommended  that the naming guidelines and  DIT structures
  2397.           defined in Annex B of  Recommendation X.521/ISO 9594-7 be used as
  2398.           the  basis for  MHS Directory  Names. Annex  C of  Recommendation
  2399.           X.402/ISO  10021-2  specifies  further  the  MHS specific  object
  2400.           classes.  The  naming   for  MHS  specific  object   classes  are
  2401.           recommended as follows:
  2402.  
  2403.                a)           The      naming     for      mhs-message-store,
  2404.                mhs-message-transfer-agent,  and mhs-user-agent  is that  of
  2405.                Application Entity in the DIT;
  2406.  
  2407.                b)    The  naming  attribute  for  mhs-distribution-list  is
  2408.                commonName.     The    organization,     organizationalUnit,
  2409.                organizationalRole,   organizationalPerson,   locality,   or
  2410.                groupOfNames  can be immediate superior to entries of object
  2411.                class mhs-distribution-list;
  2412.  
  2413.                c)  The naming for mhs-user is that of organizationalPerson,
  2414.                residentialPerson,  organizationalRole,  organizationalUnit,
  2415.                organization, or locality.
  2416.  
  2417.                NOTE - The  mhs-user object class is a  generic object class
  2418.                which  may  be  used in  conjunction  with  another standard
  2419.                object  class  for  the purpose  of  adding  MHS information
  2420.                attributes, such as  ORAddresses, to a Directory  entry. The
  2421.                means to associate attributes  of a generic object  class to
  2422.                an  entry (or  to  different entries)  named  by a  standard
  2423.                object class(es) is by defining a new (un-)registered object
  2424.                class, whose  superclass(es) is  that of  the naming  object
  2425.                class(es),  and  of  the  generic  object  class.  E.g.,  to
  2426.                associate  mhs-user attributes  in the  organizationalPerson
  2427.                entry,  a new  unregistered object class  can be  defined as

  2731.           10.1   Overview
  2732.  
  2733.           The  Security functional  group is  specified  as three  security
  2734.           classes  which are incremental  subsets of the  security features
  2735.           available in the  base standard. They are denoted  as S0, S1, and
  2736.           S2.  An implementation that  conforms to the  Security functional
  2737.           group map support one  or more of the security classes defined in
  2738.           these Implementation Agreements.
  2739.  
  2740.           S0: This  security  class  gathers  together  security  functions
  2741.           applicable   only  between   MTS-Users.  Consequently,   security
  2742.           mechanisms  are  implemented  within  the  MTS-User.  An  MTA  is
  2743.           required to  support  the  syntax  of the  security  services  on
  2744.           submission,  as the  "Kernel" supports  the  syntax on  relay and
  2745.           delivery. The MTA is not  expected to understand the semantics of
  2746.           the security services.
  2747.  
  2748.           S1:  This security class  requires secure functionality  with the
  2749.           MTS-User and MTS. The  MTS secure functionality is only  required
  2750.           to  achieve secure  access management.  As with  S0, most  of the
  2751.           security  mechanisms  are  implemented  within  an  MTS-User.  It
  2752.           primarily provides  integrity  and  authentication  between  MTS-
  2753.           Users. However, MTAs  are expected to support  digital signatures
  2754.           for  peer to peer authentication, security labelling and security
  2755.           contexts.
  2756.  
  2757.           S2:  This security  class is  a superset  of S1,  adding security
  2758.           functions  within MTAs  and the  MTS. The main  security function
  2759.           added within this group is authentication within the MTS, and, as
  2760.           a consequence, due to the  non-repudiable nature of the keys used
  2761.           for authentication, non-repudiation is also added.
  2762.  
  2763.           In addition,  each of the  three security classes has  a variant,
  2764.           denoted as S0a,  S1a, and S2a, which mandates  support of end-to-
  2765.           end confidentiality.

  2783.           be  used within  each security  class and  are identified  by the
  2784.           registered algorithm identifier.
  2785.  
  2786.           Various levels of assurance in trusted COMPUSEC functionality may

  2788.           this Implementors Agreement.

  2953.           10.2.1  Interworking between security classes
  2954.  
  2955.           A security class  can be viewed  as a tool  which can be used  to
  2956.           implement a  security policy, and is not a security policy in its
  2957.           own right but a component of a security policy.
  2958.  
  2959.           Interworking   between   implementations   supporting   different
  2960.           security classes can be achieved in terms of any common class(es)
  2961.           supported. As  specified in the  base standard, the label  of the
  2962.           message, probe  or report  must be  checked against  the security
  2963.           context by any implementation claiming conformance to classes S1,

  2980.           S1a, S2, and S2a.
  2981.  
  2982.                NOTE - Interworking  can be limited to messages  of only one
  2983.                security  class by defining a security context consisting of
  2984.                labels  with  security  policy  identifiers   of  only  that
  2985.                security class.
  2986.  
  2987.           This profile defines security policy identifiers (annex B, figure
  2988.           18)  that  corresponds to  the security  classes defined  in this
  2989.           section.  Such generic  security  policy  identifiers only  imply
  2990.           support of  the X.400  security services as  specified for  these
  2991.           security  classes in  this clause.  No other  COMSEC  or COMPUSEC
  2992.           functionality can be  assumed by use of  such policy identifiers.
  2993.           More specific security  policies may be  based on one or  more of
  2994.           the  security classes  in this  section but  will require  use of
  2995.           registered policy identifiers.
  2996.  
  2997.  
  2998.           10.2.2  Comparison of security labels
  2999.  
  3000.           The  Security Content service  ensures that the  message security
  3001.           label matches at  least one of the set of labels specified in the
  3002.           security  content  established   between  the  communicating  MHS
  3003.           entities.
  3004.  
  3005.           An MTA  which supports  the Security Content  service shall  as a
  3006.           minimum  support matching  for equality  on  the security-policy-
  3007.           identifier,   security-classification,  and   security-categories
  3008.           elements of the label.
  3009.  
  3010.                NOTE - The  basic support requirement is that  absence of an
  3011.                element shall  not  be treated  as  "any value,"  i.e.,  all
  3012.                permissible  combinations  of occurrence  and value  for the
  3013.                elements of the message security label must be elaborated in
  3014.                the security context.
  3015.  
  3016.           Any other matching rules (e.g., covering the privacy-mark element
  3017.           or  based on  alternative methods  of comparison  may be  used in
  3018.           particular  application  scenarios,  but  such specification  and
  3019.           usage will be  subject to bilateral agreement and  will depend on
  3020.           the security policy in force.
  3021.  
  3022.           The  message security  label  can be  placed  in the  per-message
  3023.           extensions  or  in the  signed  or  encrypted  data of  the  per-
  3024.           recipient message token. It is recommended  that the integrity of
  3025.           the  security label  is protected  by including  it in  the token
  3026.           signed data, or  (if the label is in  the per-message extensions)
  3027.           by  computing  the  message origin  authentication  check  on the
  3028.           message. (Support of MOAC is  optional in security classes S0 and
  3029.           S1.) Which of these labels is/are checked by the security context

  3046.           service is dictated by the security policy in force. The security
  3047.           policy should  also define  any requirements  on allowable  (per-
  3048.           recipient)  label  values  in  the  case  where  the  message  is
  3049.           addressed to multiple recipients (and thus has multiple tokens).
  3050.  
  3051.           A label  may also be  included in  the token encrypted  data with
  3052.           (confidential) end-to-end semantics.
  3053.  
  3054.  
  3055.           10.2.3  Application context
  3056.  
  3057.           When  providing the  peer entity  authentication  service, it  is
  3058.           recommended that MTAs should  not use the  "association-recovery"
  3059.           procedure of  RTSE (section 7.8.3 of X.228).  MTAs in the role of
  3060.           sender should not invoke  this procedure and MTAs in  the role of
  3061.           receiver should not accept RT-OPEN requests asking for recovery.
  3062.  
  3063.                NOTE - It is permissible for the  sending MTA to perform the
  3064.                "activity  resumption" (sec. 7.8.1 of X.228) on an existing,
  3065.                authenticated RTSE association owned by this MTA.
  3066.  
  3067.  
  3068.           10.3   Description of security classes
  3069.  
  3070.           The sections to follow  describe the security classes within  the
  3071.           Security functional  group. For each  security class, there  is a
  3072.           description of the security functionalities provided, followed by
  3073.           a table which  gives the classification for each  of the security
  3074.           services  required by that  class. Where the  classification of a
  3075.           security service  does not  change for  a higher security  class,
  3076.           then that security  service is not repeated in  the table for the
  3077.           higher security class.
  3078.  
  3079.           Figure 9 explains the column  headings used in the security class
  3080.           tables. The classifications are defined in clause 5.2.

  4044.           13.1   Introduction
  4045.  
  4046.           This clause specifies  the requirements for a  minimal 1988-based
  4047.           IPMS   implementation  (i.e.,  IPM   UA)  which  is   capable  of
  4048.           interworking with 1984-based UAs.
  4049.  
  4050.           Such a minimal 1988-based UA will have the following capabilities
  4051.           in  order to  achieve  interworking with  1984-based  UAs and  to
  4052.           facilitate migration to full 1988 operation:
  4053.  
  4054.                a)  It will continue to support content type  P2 (encoded as
  4055.                integer 2) on origination and reception;
  4056.  
  4057.                b)  It will support receipt of P2 (encoded as integer 22);
  4058.  
  4059.                c)   It  may originate  P2 encoded  as integer  22, but  the
  4060.                guidelines specified in  section 8.18.2 of X.420  (1988) are
  4061.                to be followed,  i.e., the content type shall  be encoded as
  4062.                integer 2 unless  1988 P2 protocol elements  are present.All
  4063.                IPM  UAs must  support either  MTS  Submission and  Delivery
  4064.                based on the  protocol classifications in clause A.3,  or MS
  4065.                Submission   and   Retrieval    based   on   the    protocol
  4066.                classifications in clause A.4. However, how such information
  4067.                is  conveyed to/from  the  MTS  or  MS  in  the  case  of  a
  4068.                collocated UA is a local matter, and will not necessarily be
  4069.                subject to conformance verification.

  4071.  
  4072.           13.2   Elements of service
  4073.  
  4074.           This  clause  specifies  the  requirements  for  support  of  IPM
  4075.           Elements  of  Service  by  a  UA conforming  to  the  IPM  Kernel
  4076.           Functional Group of this Agreement.
  4077.  
  4078.           The classification scheme for  support of Elements of Service  is
  4079.           as defined in clause 5.2.
  4080.  
  4081.           The  requirements for  support  of IPM  Elements  of Service  for
  4082.           origination and reception are distinguished.  Elements of Service
  4083.           which are new in the 1988 MHS standards are indicated as (1988).
  4084.  
  4085.           A UA  must support those  Basic IPM  Elements of Service  and IPM

  4263.           13.4   Body part support
  4264.  
  4265.           This  clause specifies the  requirements for support  of IPM body
  4266.           part types by a UA conforming to this Agreement.
  4267.  
  4268.           The  requirements  for  support  of   IPM  body  part  types  for
  4269.           origination  and reception  are  distinguished.  Body part  types
  4270.           which are new in the 1988 MHS standards are indicated as (1988).
  4271.  
  4272.           A UA must support those IPM body part types defined in Annex E of
  4273.           X.420 (1988) as  listed and qualified in  table 33 of Annex  A of
  4274.           this  part. If an  implementation supports a particular body part
  4275.           type for reception,  it should also be able  to support that body
  4276.           part type for reception if it is part of a forwarded message.  If
  4277.           an implementation supports origination of forwarded messages,  it
  4278.           must be capable  of forwarding every body part  that is supported
  4279.           on  reception.   The  reception  requirements on  the  UA do  not
  4280.           necessarily  include the ability  to render (display)  all of the
  4281.           characters received.   If the  message is forwarded, the  UA must
  4282.           transmit exactly equivalent characters, but not  necessarily from
  4283.           the same character set.

  4301.           supported as integer encoding (ASN.1 context-specific identifier)
  4302.           and as object identifier (externally-defined) encoding.
  4303.  
  4304.           All body parts with integer-encoded identifiers in the range 0 up
  4305.           to  and  including  16K-1 are  legal.  Body  part integer-encoded
  4306.           identifiers  corresponding  to  X.121  country  codes  should  be
  4307.           interpreted as  described in  figure 10.  These privately-defined
  4308.           body part  types are specified  as an interim measure  to provide
  4309.           backward  compatibility   with  1984  MHS   implementations.  For
  4310.           interworking between  UAs  based  on  the  1988  (or  later)  MHS
  4311.           standards, it is strongly recommended that the externally-defined
  4312.           body part be used instead.

  4451.           13.5.1  Implementation of the IPM MS with 1984 systems
  4452.  
  4453.           While  the Message  Store  is  part of  the  1988 MHS  standards,
  4454.           implementation of  MS services  with a 1984  MTA is  possible. In
  4455.           order   to   interoperate   with    other   1984   MHS   systems,
  4456.           implementations  with  this configuration  should  adhere to  the
  4457.           following guidelines:
  4458.  
  4459.                a)  The UA must generate 1984 P2 PDUs;
  4460.  
  4461.                b)   The UA must identify  the content protocol as integer 2
  4462.                to the MS;
  4463.  
  4464.                c)  The  MS must be collocated  with the MTA unless  1988 P3
  4465.                support is provided on the 1984 MTA as well.
  4466.  
  4467.           To meet these guidelines, the UA may be implemented as follows:
  4468.  
  4469.                a)   The UA  could conform  to X.420  (1984),  with 1988  UA
  4470.                extensions for utilizing the MS services;
  4471.  
  4472.                b)  The UA could be a 1988 UA with restrictions  on protocol
  4473.                elements  generated and by  identifying the content  type as
  4474.                integer 2 rather  than 22. No 1988-specific  elements should
  4475.                be generated.
  4476.  
  4477.           Details  of the interface  between the 1988  MS and  the 1984 MTA
  4478.           when collocated are beyond the scope of these Agreements.

  4572.           "Conversion  Prohibition in  Case  of  Loss  of  Information"  is
  4573.           requested, then the MTA is  not allowed to perform the conversion
  4574.           if loss of information may occur, according to the classification
  4575.           in clause 2.1 of X.408.  
  4576.  
  4577.           If   the  General  Text   body  part   type  is   supported,  the

  4667.           14.1   Introduction
  4668.  
  4669.           This  clause specifies  the requirements  for an   EDI  Messaging
  4670.           Service   (EDIMS).     These   requirements   are      based   on
  4671.           Recommendations X.435 and F.435 which define the  P(edi)  content
  4672.           type and outline various EDIMS operational scenarios.
  4673.  
  4674.           This EDIMS  Implementation Agreement  separates the  functions of
  4675.           the base  standard into a  Kernel and optional  Functional Groups
  4676.           (FGs).   These  functional  groups  may be  used  to support  the
  4677.           different scenarios of the EDIMS.
  4678.  
  4679.           The following functional groups are defined:
  4680.

  5032.           functionality required to  provide security for EDIMs  and EDINs.
  5033.           These  security  features are  specific  to  the EDIMS,  and  are
  5034.           described in X.435.
  5035.  
  5036.           As the interface  between the EDI Messaging (EDIMG)  user and the
  5037.           EDI-UA is outside  the scope of this document, implementations of
  5038.           the   security  mechanisms  can  be  implemented  as  a  discrete
  5039.           hardware/software component or within the EDI-UA.
  5040.  
  5041.                NOTE - There  are alternative methods of  providing security
  5042.                to the EDIMG  user.  For example, the EDI-UA  may just avail
  5043.                itself of the  (content-type independent) security  services
  5044.                provided or  supported by the  (1988) MHS  and described  in

  5053.           The EDIMS Security functional group is specified as  two security
  5054.           classes, denoted  EDI-A  and  EDI-B.    Note  that  the  services
  5055.           provided below are provided, in  some cases, by 1988 MHS security
  5056.           elements in the P1 (and P3) envelope.  For example, depending  on

  5312.           addition to the requirements stated in this document. Conformance
  5313.           to  this  Agreement  requires the  ability  to  exchange messages
  5314.           without use of bilateral agreements.

  5316.           In  order  to achieve  a more  precise definition  of conformance
  5317.           requirements  according  to  the  functionality  supported by  an
  5318.           implementation,  the  concept  of   Functional  Groups  has  been
  5319.           introduced. A  Functional Group is  a set of related  Elements of
  5320.           Service and associated protocol elements which provide a discrete
  5321.           area of functionality.
  5322.  
  5323.           Conformance to  this Agreement  requires as  a  minimum that  all
  5324.           Mandatory Elements of  Service listed in this  part are supported
  5325.           in the manner defined in the MHS standards, as qualified  in this
  5326.           Agreement,  for  each  of  the  Functional  Groups  claimed.  Any
  5327.           Optional  Elements of Service  for which support  is claimed must
  5328.           also  be  supported  as  defined  in the  MHS  standards  and  as
  5329.           qualified  in  this  Agreement.  Pragmatic constraints  shall  be
  5330.           observed  as  specified  in  the  CCITT  X.400 (1988)  Series  of
  5331.           Recommendations. It is not necessary to implement the recommended
  5332.           practices  of annex  D  in  order to  claim  conformance to  this
  5333.           Agreement.
  5334.  
  5335.           Conformance  requirements  for support  of  Functional Groups  by
  5336.           particular configuration types (see clause 1) are listed in table
  5337.           30.  An   implementation  may   claim  conformance  to   multiple

  5378.            | 1  There are three conformance classes defined for the      |
  5379.            |    MT Kernel in clause 17.1.                                |
  5380.            | 2  Optional elements of a context-specific UA need not be   |
  5381.            |    supported in the MT Kernel in this configuration, for    |
  5382.            |    example Probe and Deferred Delivery Cancellation.        |
  5383.            | 3  The designation of a '+' in a configuration (e.g.,       |
  5384.            |    'MTA+MS') implies that there is no exposed protocol in   |
  5385.            |    the interface between the two components.                |
  5386.            | 4  There are two conformance levels defined in clause       |
  5387.            |    17.2 for MS support.                                     |
  5388.            | 5  At least one of the content-specific functional groups   |
  5389.            |    must be supported.                                       |
  5390.            | 6  The content-specific functional groups may include       |
  5391.            |    requirements for levels of support by an MS and/or MTA   |
  5392.            |    (e.g., in terms of attributes supported, conversion      |
  5393.            |    requirements, etc.). In table 29, the support of a       |
  5394.            |    content-specific functional group by the MS only implies |
  5395.            |    support of the MS requirements for that content type     |
  5396.            |    (i.e., attribute). Similarly, support in the MTA for a   |
  5397.            |    content-specific functional group only implies support   |
  5398.            |    for the MTA requirements for that content type (e.g.,    |
  5399.            |    conversion).                                             |

  5422.           17.1   MT Kernel Conformance Classes
  5423.  
  5424.           The MT Kernel conformance classes are:
  5425.  
  5426.                a)  A class "A"  MT Kernel implementation conveys a message,
  5427.                probe, or report to another MT Kernel using standard  means.
  5428.                A class "A" MT  Kernel is specifically implemented in  order
  5429.                to  transfer  messages,  probes,   and  reports  which  have
  5430.                previously been transferred and need not support  submission
  5431.                and delivery.  A  class  "A"  MT Kernel  may  perform  other
  5432.                activities  such as  originate reports,  expand distribution
  5433.                lists, and perform conversions.
  5434.  
  5435.                b)     A  class   "B"  MT  Kernel   implementation  supports
  5436.                submission,  delivery,  and transfer  using  standard means,
  5437.                i.e., P3 and  P1. A class 'B' MT Kernel need not support the
  5438.                transfer  of  previously  transferred messages,  probes,  or
  5439.                reports.
  5440.  
  5441.                c)   A class  "C" MT Kernel  implementation requires support
  5442.                for transfer of  messages, probes, and reports to another MT
  5443.                Kernel using standard means. A  class "C" MT Kernel does not
  5444.                require support  for the transfer  of previously transferred
  5445.                messages, probes,  and reports,  and message  submission and
  5446.                delivery is achieved by non-standard means.
  5447.  
  5448.           An MTA may conform  to one or more of the MT  Kernel classes. For
  5449.           example, a class "B" or "C" MT Kernel which supports the transfer
  5450.           of previously transferred  messages, probes, and reports  is also
  5451.           conformant to  a  class  'A' MT  Kernel.  Figure  11  illustrates
  5452.           several combinations of MT Kernel conformance classes. Additional
  5453.           combinations are possible.

  5489.  
  5490.           The MS conformance levels are:
  5491.  
  5492.                a)    A Basic  MS  only  requires  support for  the  General
  5493.                Attributes as specified in clause A.8, basic column of table
  5494.                43;
  5495.  
  5496.                b)  An enhanced MS requires support for more of the  General
  5497.                Attributes as specified in clause A.8 (enhanced column);
  5498.  
  5499.                c)   A  Secure  MS additionally  requires  support  for  the
  5500.                attributes as specified in clause A.9.
  5501.  
  5502.           For  content-specific  MS   requirements,  see  the   appropriate
  5503.           content-specific clauses.
  5504.  
  5505.  
  5506.           17.3   EDI-UA conformance
  5507.  
  5508.           The EDI functional group requires  the support of the EDIFACT and
  5509.           ANSI X12 EDI syntaxes.
  5510.  
  5511.  
  5512.           18  Management domain agreements
  5513.  
  5514.           The  sections  above  describe agreements  among  implementors of
  5515.           particular X.400  components (e.g.,  MTAs, UAs,  MSs). There  are
  5516.           some agreements that don't apply to a single X.400 component, but
  5517.           instead  apply  to an  entire  domain of  X.400  components. This
  5518.           section details  any requirements for X.400  domains, independent
  5519.           of   those  for  individual  X.400  components.  A  single  X.400
  5520.           component  cannot  be   conformance  tested   for  these   domain
  5521.           requirements, but for a domain  to claim to be "operationally OIW
  5522.           compliant," it must abide by the rules stated below.
  5523.  
  5524.  
  5525.           18.1   Management domain names
  5526.  
  5527.           This section contains requirements on matters being considered by
  5528.           the  U. S.  CCITT  Study  Group D  for  national decisions.  Such
  5529.           decisions are  likely to supersede the relevant  portions of this
  5530.           clause.
  5531.  
  5532.           The Implementation Agreements for  1984-based MHS implementations
  5533.           requires  that  all  Management Domain  Names  (both  Private and
  5534.           Administration) shall  be unique within the U.  S. This is also a
  5535.           requirement for 1988-based MHS implementations.
  5536.  
  5537.           A "Construction Syntax" is defined,  which uses a registered  OSI

  5556.           e.g., ADMD and  PRMD). The constructed combinations based on this
  5557.           "root" will be guaranteed  to be unique, and thus  be safely used
  5558.           as MHS MD names in the United States. Other countries may wish to

  5640.                syntax (those having  a "+" in them) are  atomic values from
  5641.                the point  of view of  the MTA --  in particular, it  is not
  5642.                permissible for the  MTA to route on components  of the PRMD
  5643.                name.
  5644.  
  5645.                2    The  construction rules  are  such  that  if ABC  is  a
  5646.                Registered  National Organization  Name, then  the  owner of
  5647.                that name controls the MHS Domain Name space including "ABC"
  5648.                and "ABC+<anything>," but not "ABC<anything>."
  5649.  
  5650.                3  A "+" is legal in an ANSI provided name.
  5651.  
  5652.                4  If  a Registered Organization  Name already contains  the
  5653.                construction operator ("+" sign),  then in order to use  the
  5654.                name as an <MDName>, its owner must also register the "root"
  5655.                which precedes the  first "+" sign, with the  US Register of
  5656.                Organization  Names.  (e.g.,  company  B+Z+P  would  need to
  5657.                register "B"  to be  able to use  the "constructed"  name of
  5658.                B+Z+P.)
  5659.  
  5660.                5   For the special  case of the construction  operator ("+"
  5661.                sign) being the  first character of a  Nationally Registered
  5662.                Name,  no special  action  is  required  beyond  its  normal
  5663.                registration with the US Registry of Organization Names.
  5664.  
  5665.                6         If     the     sub-authority     determined     by
  5666.                <NationalOrganizationName>       so        wishes,       the
  5667.                <OrganizationallyDeterminedPart>  can  be  constructed using
  5668.                rules  similar to  the above,  resulting  in a  hierarchical

  5715.           18.2   Use of ADMD names
  5716.  
  5717.           This subsection  was developed by  an X.400 SIG working  group in
  5718.           April, 1990. It  contains extremely controversial positions  that
  5719.           invoke national, commercial,  and quality of service  issues. The
  5720.           OIW  may  not  be  the  correct  forum  to  make  these  national
  5721.           decisions. Until these  decisions can  be reached  or a  national
  5722.           forum  established, this section remains as  a placeholder in the
  5723.           OIW X.400 SIG Working Text document only.
  5724.  
  5725.                NOTE  - Version  2 of  the CCITT  X.400 Implementors  Guide,
  5726.                dated  16  March  1990,  allows  for  a  single  zero  ("0")
  5727.                character as the  ADMD name for the  case of a PRMD  that is
  5728.                not reachable from  any ADMD. The following  discussion does
  5729.                not apply to such PRMDs.
  5730.  
  5731.           A PRMD may be directly connected  to more than one ADMD. Since  a
  5732.           PRMD  may not alter  the originators ORAddress,  the Country/ADMD
  5733.           name  pair provided  in the  Originator ORAddress  may  not match
  5734.           those of the first ADMD to receive the message from the PRMD. The
  5735.           first ADMD is required to accept  such messages and may not alter
  5736.  
  5737.                                           76
  5738.  
  5739.  
  5740.  
  5741.  
  5742.  
  5743.  
  5744.  
  5745.  
  5746.  
  5747.  
  5748.  
  5749.  
  5750.           
  5751.  
  5752.           the originator's ORAddress.
  5753.  
  5754.           Any message  originated  by  a PRMD  must  have  an  Originator's
  5755.           ORAddress that either uses  the single space ADMD name  or uses a
  5756.           Country/ADMD  name  pair  for  an  ADMD  to  which  the  PRMD  is
  5757.           connected. (In both cases the Country name is required.)
  5758.  
  5759.           The X.400 Recommendations  have defined a mechanism  that enables
  5760.           PRMDs connected to multiple ADMDs to enter a single space as  the
  5761.           ADMD  name. To  support  this,  these  agreements  recognize  two
  5762.           classes  of ADMDs. ADMDs  in the first  class, "space-supporting"
  5763.           ADMDs, must be able to route on PRMD name, independently from the
  5764.           ADMD name. Furthermore, the  space-supporting ADMDs must  arrange
  5765.           their routing  configuration such  that all  PRMDs are  reachable
  5766.           from  all ADMDs. PRMDs using  the single space  ADMD name must be
  5767.           connected to at least one space-supporting ADMD.
  5768.  
  5769.           ADMDs  in the other class, "non-space-supporting" ADMDs, must, at
  5770.           a minimum,  route messages for  which the ADMD  name is  a single
  5771.           space to a  space-supporting ADMD (in the indicated  country). It
  5772.           is hoped that in the long term,  all ADMDs will be able to  route
  5773.           on the PRMD name when the ADMD name is a single space.
  5774.  
  5775.  
  5776.           18.3   Uniqueness of MTS Identifiers within a management domain
  5777.  
  5778.           When generating an  IA5String in an MTS Identifier, each MTA in a
  5779.           domain must ensure  that the string is unique  within the domain.
  5780.           This shall be done  by providing an MTA designator with  a length
  5781.           of  12  octets   which  is  unique  within  the   domain,  to  be
  5782.           concatenated to  a per message  string with maximum length  of 20
  5783.           octets.
  5784.  
  5785.           Two pieces of information, the  MTA name and MTA designator, need
  5786.           to  be registered  within an  MD to  guarantee uniqueness.   This
  5787.           registration facility need not be automated.  If the MTA  name is
  5788.           less  than or equal to  12 characters, it  is recommended that it
  5789.           also be used as the MTA designator.

  5820.           MHS protocol specifications
  5821.  
  5822.           Tables 31 through 48 specify the requirements for  support of MHS
  5823.           protocol elements for conformance to this Agreement. It should be
  5824.           noted that the tables specify minimum support for  conformance to
  5825.           the  relevant Kernel functional groups and where appropriate also
  5826.           specify enhanced support  requirements where one or  more further
  5827.           functional groups are claimed. All  element support is subject to
  5828.           further review  and may  be upgraded  in later  versions of  this
  5829.           Agreement.
  5830.  
  5831.           Within  the  classification  tables   (32-48),  the  column   "S"
  5832.           indicates the  classification from  the base  standards. This  is
  5833.           provided for  reference purposes only  and is  intended to be  in
  5834.           agreement with the base standards.
  5835.  
  5836.           The protocol support  classification scheme used in  this version
  5837.           of this Agreement is described below. However, it should be noted
  5838.           that the  scheme is currently  under review  both within the  OIW
  5839.           X.400 SIG  and in the  EWOS/ETSI MHS groups  and is likely  to be
  5840.           revised for later versions of this Agreement.
  5841.  
  5842.           The  classification of support  for a protocol  element specifies
  5843.           the requirements for implementations conforming to this Agreement
  5844.           to  be  able to  generate,  receive  and  process  that  protocol
  5845.           element, as appropriate (the  'receiving' role includes  relaying
  5846.           where  appropriate).  The  classification  of  support  for  each
  5847.           protocol element is relative to that for its containing  element.
  5848.           Where  sub-elements within a  containing element are  not listed,
  5849.           then their support classification shall be assumed to  be that of
  5850.           the containing element. Where the range of values to be supported
  5851.           for an element is not  specified, then all values defined in  the
  5852.           base standard shall be supported.
  5853.  
  5854.           The classifications have been revised. The former classifications
  5855.           relate to the classifications in Part 7 of  the Stable Agreements

  5906.           another MHS entity (MTA, MS, or UA), the MS or MTA is required to
  5907.           preserve  the semantics  of  that  protocol  element in  the  PDU
  5908.           conveyed. Notwithstanding the above, criticality must be observed

  5953.                in the particular context according to the base standard.
  5954.  
  5955.           Where  the dynamic  behavior  of  protocol  elements need  to  be
  5956.           specified, the following classification scheme is used:
  5957.  
  5958.                Mandatory  (m):   The  protocol  element   shall  always  be
  5959.                implemented and  generated.  On  reception,  correct  action
  5960.                shall  be taken  as specified  in the  base standard,  or as
  5961.                qualified or specified  in these Agreements. Absence  of the
  5962.                corresponding protocol  element shall cause  the appropriate
  5963.                abstract error to be generated.
  5964.  
  5965.                Excluded (x): The protocol  element shall not be present  or
  5966.                it must be  possible to prevent its use.  Its presence shall
  5967.                cause the appropriate abstract error to be generated.
  5968.  
  5969.           Dynamic  conformance classifications  are indicated  in  a single
  5970.           column of each of the Protocol Element tables. The classification
  5971.           applies  to the usage only of the  protocol elements which have a
  5972.           static classification.
  5973.  
  5974.           There  are two  types  of tables  defining  support for  protocol
  5975.           elements:  the first is a base table that contains and classifies
  5976.           all  protocol elements,  and the  second is  a delta table  for a
  5977.           functional group.
  5978.  
  5979.           Functional  group tables need  only list those  protocol elements
  5980.           for   which  the  functional   group  has  changed   the  support
  5981.           requirements  from  the   base  table.     Additional  containing
  5982.           constructor elements may  be listed in  order to provide  context
  5983.           information.
  5984.  
  5985.           If the functional  group changes the  support requirements for  a
  5986.           given  element it must be classified in the delta table.  Changes
  5987.           should  only place more restrictions on the required support, for
  5988.           example  changing an  optional element  to  be either  mandatory,

  15798.           this Agreement.  Elements of Service which are  not referenced in

  15811.           messages is clarified:
  15812.  
  15813.                a)    The encoded  information  types of  the  message being
  15814.                forwarded  should be reflected  in the new  original encoded
  15815.                information types being generated.
  15816.  
  15817.                b)  If forwarding a privately defined body  part (see figure
  15818.                10),  the originator of the forwarding message shall set the
  15819.                original encoded  information types  in the  P1 envelope  to
  15820.                Undefined for that body part.

  15854.           This clause  provides guidelines  on areas  not addressed  by the
  15855.           base standards. These guidelines  have been produced in  order to
  15856.           promote awareness  of interim solution  to problems  as agree  by
  15857.           members of  the  OIW X.400  SIG.  However implementors  of  these
  15858.           recommended practices  should note  that it  is not necessary  to
  15859.           follow  the recommended  practices  when claiming  conformance to
  15860.           these agreements.
  15861.  
  15862.           Implementors  should  also note  that  future  standardization by
  15863.           CCITT  and ISO/IEC on area  covered by this  clause may result in
  15864.           different solutions to those proposed in this clause.

  15867.           D.1    Printable String
  15868.  
  15869.           There are  existing mail systems that include a small set of non-
  15870.           Printable  String characters  in their  identifiers.   For  these
  15871.           systems  to communicate with MHS systems, either for pass-through
  15872.           service or  delivery to MHS  users, gateways will  be employed to
  15873.           encode  these special  characters into  a  sequence of  Printable
  15874.           String  characters.  This  conversion  should be performed by the
  15875.           gateway  according to  a common  scheme  and before  insertion in
  15876.           Domain Defined Attributes, which are intended to carry electronic
  15877.           mail identifiers.  MHS UAs may also perform such conversions.
  15878.  
  15879.           It is  recommended that  the following  symmetrical encoding  and
  15880.           decoding  algorithm   for  non-Printable  String   characters  be
  15881.           employed.  The encoding algorithm maps an ASCII representation to
  15882.           a  PrintableString  representation.    Any  non-printable  string
  15883.           characters not specified in table 49 are covered  by the category

  16259.  
  16260.           To ease interworking with  1984 implementations when transferring
  16261.           Office Document  Architecture (ODA) documents,  the following are
  16262.           recommended for 1988 implementations:
  16263.  
  16264.                a)     Origination  UA   implementing  1988   Implementation
  16265.                Agreements.  The 1988  will generate  the  ODA according  to
  16266.                CCITT Recommendation T.411 Annex E for the destination UA(s)
  16267.                implementing   1988   Implementation  Agreements.   If   the
  16268.                destination UA supports  1984 Implementation Agreements, the
  16269.                approach as described in section 7.12.8 is recommended.
  16270.  
  16271.                b)      Recipient   UA  implementing   1988   Implementation
  16272.                Agreements. The recipient system will be  able to handle the
  16273.                ODA bodypart  in P2 (1984) as  defined in part 7,  B.8.1 for
  16274.                interworking with 1984 implementation, and will also be able
  16275.                to handle  the ODA  bodypart as  defined in the  appropriate
  16276.                base standards.
  16277.  
  16278.                c)  MTA downgrading rules. When transferring an P22 with ODA
  16279.                body part in P22 as described  in T.411 to an 1984 MTA,  the
  16280.                EITs identified by ODA Object Identifiers are mapped to bits
  16281.                0 and 10 of the built-in EITs.
  16282.  
  16283.           If  the UA does  not register to  support P22 or  ODA bodypart, a
  16284.           Non-Delivery-Report will be generated as required.

  16424.           On the  basis of the Externally Defined  body part type, all body
  16425.           part types are divided into two important classes as follows:
  16426.  
  16427.                a)   basic:  Said  of any  body part type  except Externally
  16428.  
  16429.                                          238
  16430.  
  16431.

  16440.  
  16441.  
  16442.           
  16443.  
  16444.                Defined.   All  basic  body  part types  are  denoted by  an
  16445.                integer (an ASN.1  context-specific tag) and are  defined in
  16446.                section 7.3 of X.420.
  16447.  
  16448.                b)  extended:  Said of the Externally Defined body part type
  16449.                restricted  to  any  one   value  of  the   Direct-reference
  16450.                component  of the  Data  component  of  such  a  body  part.
  16451.                Denoted by an Object Identifier.
  16452.  
  16453.           Annex B of Recommendation X.420 defines some (but not necessarily
  16454.           all) extended body part types.
  16455.  
  16456.  
  16457.           D.5.2   Use of equivalents of basic body part types
  16458.  
  16459.           For  each basic  body part  types, section B.1  of Recommendation
  16460.           X.420 defines an equivalent extended body part type.  In order to
  16461.           facilitate  interworking with 1984 systems, use of these extended
  16462.           body part  types is  not recommended; the  basic body  part types
  16463.           should be used instead.
  16464.  
  16465.           Editor's Note: The requirements  of this  clause may  change when
  16466.                          interworking  with  1984   systems  is  no  longer
  16467.                          critical.
  16468.  
  16469.  
  16470.           D.5.3   Use of General Text body part type
  16471.  
  16472.           Unless otherwise  specified in  these agreements  (e.g., IA5Text,
  16473.           6937Text, Teletex) the  General Text body part as  defined in ISO
  16474.           10021-7   Annex  B.2  is   the  preferred  means   of  supporting
  16475.           unstructured text  body parts.   The  character set  registration
  16476.           referred to in that annex is provided by ECMA.
  16477.  
  16478.  
  16479.           D.5.4   Use of File Transfer body part type
  16480.  
  16481.           The File Transfer body part type is the recommended mechanism for
  16482.           the  exchange  of complex  computer  data via  intra-  and inter-
  16483.           company  X.400 messages.   It enables automatic  type recognition
  16484.           for  the file being  sent and, possibly,  automatic invocation of
  16485.           the appropriate application necessary to process the data.
  16486.  
  16487.  
  16488.           D.5.4.1   Encoding of General Identifier
  16489.  
  16490.           In  order  to  optimize  the  machine-processing  of  information
  16491.           encoded  in  the Parameters  and  to enable  registration,  it is
  16492.           recommended  that,  if  present,  General  Identifiers should  be
  16493.           encoded as Object Identifiers.

  16511.           D.5.4.2   Encoding of Contents Type
  16512.  
  16513.           It is recommended that the  Contents Type parameter be encoded as
  16514.           document  type.    The encoding  as  constraint-set-and-abstract-
  16515.           syntax has  been provided  only for  backward compatibility  with
  16516.           FTAM and its use is discouraged.
  16517.  
  16518.  
  16519.           D.5.4.3   Encoding of application specific information
  16520.  
  16521.           The type of a file can be considered from several perspectives:
  16522.  
  16523.                a)  As a specific data structure consisting of a sequence of
  16524.                presentation data values  - the position  taken by the  FTAM
  16525.                standard;
  16526.  
  16527.                b)  As  the output of a  certain application - the  position
  16528.                taken  by e-mail users  requiring the interchange  of office
  16529.                documents.
  16530.  
  16531.  
  16532.           The fact that registered OSI document types have to be recognized
  16533.           by  FTAM  implementations  and  be  described  according  to  the
  16534.           requirements of ISO/IEC  9834-2 "Registration procedures  for OSI
  16535.           document   types"  makes  use  of  the  Contents  Type  parameter
  16536.           inappropriate for expressing point of view (b).
  16537.  
  16538.           Considering   that   the  environment   parameter   "application-
  16539.           reference" could describe not only the application that generated
  16540.           a document but,  more generally, the application-level  format of
  16541.           the  document, it  is recommended  that the  values given  to the
  16542.           "application-reference" parameter component be Object Identifiers
  16543.           associated with such a format.
  16544.  
  16545.           Example:   If  an Object  Identifier has  been associated  with a
  16546.           certain word-processing  file format then  this Object Identifier
  16547.           should be  used as  the value of  "application-reference" when  a
  16548.           file of  that format  is carried  by a  File Transfer  body part,
  16549.           while the  Content Type  parameter should have  as its  value the
  16550.           Object  Identifier  associated   with  the  "unstrucutred-binary"
  16551.           document type.
  16552.  
  16553.  
  16554.           D.5.4.4   EITs for the File Transfer body part
  16555.  
  16556.           It is  recommended to  use only  the id-eit-file-transfer  Object
  16557.           Identifier in association with the File Transfer body part.
  16558.  
  16559.           The use of EITs describing  other parameters of the File Transfer
  16560.  
  16561.                                          240

  16573.  
  16574.           
  16575.  
  16576.           body  part such as  contents types, application  references, etc.
  16577.           would force all potential recipients to register a possibly large
  16578.           number of EITs in order to avoid non-delivery of messages.
  16579.  
  16580.  
  16581.           D.5.5   Use of other extended body part types
  16582.  
  16583.           The  following are  guidelines regarding  the  use of  Externally
  16584.           Defined  body  part types  not  defined  in  the X.400  or  other
  16585.           standards: 
  16586.  
  16587.                a)   Use of Parameters  component: In simple cases,  to ease
  16588.                the  integration  of  applications  to  X.400  systems,  the
  16589.                Parameters component need not be used.
  16590.  
  16591.                b)   Use  of Data  component: For  each different  format of
  16592.                data, different  Object Identifiers  for the  Data component
  16593.                are recommended. If an  application chooses to use  ASN.1 to
  16594.                format  the data to  achieve a single  representation across
  16595.                platforms,  the single-ASN1-type  encoding choice  should be
  16596.                used. Otherwise:
  16597.  
  16598.                     1)  The  octet- (i.e., byte) aligned choice  is used if
  16599.                     the data format is octet-aligned; or,
  16600.  
  16601.                     2)   The arbitrary choice  is used if  the data is bit-
  16602.                     aligned.
  16603.  
  16604.                c)   Assignment  of Object  Identifiers: Object  Identifiers
  16605.                need to be assigned for the EXTERNALs, and these identifiers
  16606.                for  the Parameters and Data components should be different.
  16607.                The Object  Identifier for  an EXTERNAL  also indicates  the
  16608.                syntax of the data encoding,  i.e., whether single-ASN1-type
  16609.                or octet-aligned or bit-aligned is being used.
  16610.  
  16611.                NOTE - Use of proprietary Externally Defined body part types
  16612.                is recommended only if the extended body part  types already
  16613.                defined  in the  standards do  not  provide the  apporpriate
  16614.                functionality.
  16615.  
  16616.           In  order  to communicate  with  1984  systems,  the use  of  the
  16617.           Bilaterally Defined body part is recommended.

  16619.  
  16620.           D.5.6   Obtaining object identifiers
  16621.  
  16622.           There are many ways to obtain object identifiers. One such way is
  16623.           described as follows:
  16624.  
  16625.                a)  The application provider  obtains a unique Numeric  Name
  16626.  
  16627.                                          241
  16628.  
  16629.  
  16630.  
  16631.  
  16632.  
  16633.  
  16634.  
  16635.  
  16636.  
  16637.  
  16638.  
  16639.  
  16640.           
  16641.  
  16642.                form for their organization from ANSI, as described  in ANSI
  16643.                ISSB 840 and ISSB 843, and appends this  number form to {iso
  16644.                (1)  member-body (2) US (840)}  to form an object identifier
  16645.                denoting their organization.
  16646.  
  16647.                b)    The  application provider  (organization)  allocates a
  16648.                series of numbers  to identify the application  data format;
  16649.                these  numbers   are  appended  to  the   object  identifier
  16650.                constructed in step (i) to form an object identifier that is
  16651.                globally  unique. It  is  recommended  that the  application
  16652.                provider  (organization) use  a  hierarchical structure  for
  16653.                identifying their data  types to ease the  administration of
  16654.                the identifiers.
  16655.  
  16656.           For  example, company  PCSoftware Inc.  obtains the  organization
  16657.           number "999" from ANSI.  The PCSoftware SpreadSheet file for  MS-
  16658.           DOS might be assigned the following object identifier.
  16659.  
  16660.                NOTE -  ASN.1 notation is  used. The numbers  in parentheses
  16661.                form  the identifier,  the  associated  words  describe  the
  16662.                number.
  16663.  
  16664.                { iso (1) member-body (2) US (840) PCSoftware Inc. (999) MS-
  16665.                DOS-Application (1) SpreadSheet (3) Data (1) }
  16666.  
  16667.  
  16668.           D.6    Privacy Enchanced Mail body part
  16669.  
  16670.           This clause describes  a mechanism to convey an  Internet Privacy
  16671.           Enhanced Mail (PEM) message across an X.400 MHS. PEM is described
  16672.           in Internet RFCs 1113, 1114, and 1115 and their successors.
  16673.  
  16674.           The general Internet mail message format is described in RFC 822.
  16675.           Mapping  of RFC  822 messages  to and  from X.400  Inter Personal
  16676.           Messages is  described in RFC 987 for 1984  X.400 and in RFC 1148
  16677.           for 1988 X.400.
  16678.  
  16679.           The PEM message is  conveyed as a P2(2) body part. All of the RFC
  16680.           822  header information  is conveyed  in the  P1 envelope  and P2
  16681.           header per  RFC 987 and  RFC 1148. The PEM  message (encapsulated
  16682.           security  header  and,  possibly   encrypted,  message  text   as
  16683.           described in RFC 1113) is conveyed in  a single body part. On the
  16684.           X.400 side, this body part may be manipulated like any other body
  16685.           part; e.g., it may be included in a multi-part body.
  16686.  
  16687.           For 1988 (P22), the PEM body part is  externally defined and does
  16688.           not require parameters. This definition is provided in figure 23.

  16775.                  algorithms
  16776.  
  16777.           This  clause describes  one  method  of  providing  the  security
  16778.           services   of  class  S0A  when  using  asymmetric  (public  key)
  16779.           cryptographic algorithms.  It is recommended that this method  be
  16780.           used  unless  the  security  requirements  or   policy  specifies
  16781.           otherwise.  Asymmetric  cryptographic algorithms such as  RSA are
  16782.           used  to  provide digital  signatures in  support of  the content
  16783.           integrity   and   (end-to-end)  message   origin   authentication
  16784.           services, as  well  as  proof  of  delivery.    Since  asymmetric
  16785.           algorithms are  used,  the  non repudiation  of  origin  and  non
  16786.           repudiation of  delivery services of  security class S2  are also
  16787.           provided. Content confidentiality is provided using a combination
  16788.           of symmetric and asymmetric encryption.  The following paragraphs
  16789.           discuss the  protocol elements used to provide these services, as
  16790.           well as certificate management and other issues.
  16791.  
  16792.  
  16793.           D.9.1   Protocol elements
  16794.  
  16795.           The following protocol  elements are provided by  the originating
  16796.           UA  in the  submission envelope  in support  of the  S0A security
  16797.           services.
  16798.  
  16799.           Content:   If the  content confidentiality services  is required,
  16800.           the   message    content   is   encrypted   under   the   content
  16801.           confidentiality key.
  16802.  
  16803.           Content  Integrity Check:  This per-recipient security element is
  16804.           a signature  over the message  content, and provides  the content
  16805.           integrity,  message origin authentication, and non repudiation of
  16806.           origin services if content confidentiality is not required.   (If
  16807.           the message is encrypted, the content integrity check is included
  16808.           in the message token.)  
  16809.  
  16810.                NOTE  - The message  origin authentication check  provides a
  16811.                single  signature, rather  than a  signature per  recipient,
  16812.                thus reducing total  message size in the case where multiple
  16813.                recipients  are present.  However, support for this protocol
  16814.                element is optional for security  class S0.  In addition, it
  16815.                is computed  over the  message  content as  sent (i.e.,  the
  16816.                encrypted content if  content confidentiality is used).   If
  16817.                the content  is encrypted,  this protocol  element does  not
  16818.                truly provide  non repudiation  of the  unencrypted content.
  16819.                In this  case, smaller message  size was traded off  for the
  16820.                additional service of non repudiation.
  16821.  
  16822.           Proof Of Delivery  Request:  This per-recipient  security element
  16823.           is used to request the recipient to generate a proof of delivery,

  16840.           in the  case where content  confidentiality is not used.   (Where
  16841.           content confidentiality is used, the proof of delivery request is
  16842.           included in the message token, as shown below.)
  16843.  
  16844.           Originator Certificate:  This security element is a set of one or
  16845.           more  certificates  which the  recipient  may use  to  obtain the
  16846.           originator's public key.  For example, it might contain the chain
  16847.           of certificates  from the  originator, through  the certification
  16848.           hierarchy to a top-level certification authority.
  16849.  
  16850.           Message Token:   The  asymmetric message  token conveys  security
  16851.           information from  an originator to a  single recipient.  It  is a
  16852.           signed structure,  some of  whose fields may  be encrypted.   The
  16853.           message  token is  used  only  when  content  confidentiality  is
  16854.           desired,  and  supports  the content  integrity,  message  origin
  16855.           authentication, content  confidentiality, and non  repudiation of
  16856.           origin  services.   The following  fields are  required, and  all
  16857.           other fields are optional:
  16858.  
  16859.                -  Signature Algorithm Identifier:  The algorithm identifier
  16860.                of the asymmetric algorithm used to sign the token.
  16861.  
  16862.                -  Recipient Name:  The  OR Address and/or Directory Name of
  16863.                the recipient with whom the  token is associated.  Since the
  16864.                encrypted  portion of  the  token  is  encrypted  under  the
  16865.                recipient's public key, it is recommended that the directory
  16866.                name be included, since the recipient's certificate contains
  16867.                his/her directory name rather than OR Address.
  16868.  
  16869.                -  Time:  The time of day when the token was generated.
  16870.  
  16871.                -   Signed  Data:  The  following fields are  signed but not
  16872.                encrypted:
  16873.  
  16874.                a)    Content  Confidentiality  Algorithm  Identifier:   The
  16875.                algorithm to be used to encrypt the message content.
  16876.  
  16877.                b)   Proof  of Delivery  Request:   This element is  used to
  16878.                request the recipient  to compute a  proof of delivery  over
  16879.                the received message.
  16880.  
  16881.                -   Encrypted Data:   These fields  are encrypted  under the
  16882.                recipient's public key:
  16883.  
  16884.                c)  Content Confidentiality Key:   The symmetric key used to
  16885.                encrypt the message content.
  16886.  
  16887.                d)  Content Integrity Check:  A signature on the unencrypted
  16888.                message  content.  If  content confidentiality  is required,
  16889.                this element provides the  content integrity, message origin

  16907.                This  signature is encrypted in order to protect against the
  16908.                "low entropy" attack  described in Internet  RFC 1113.   (In
  16909.                RFC  1113,  the  signature is  encrypted  under  the content
  16910.                confidentiality key.)  
  16911.  
  16912.  
  16913.                NOTE - The encrypted portion of the token will then comprise
  16914.                two RSA encryption blocks.
  16915.  
  16916.           The following element  of service is generated by  the recipient,
  16917.           if requested by the originator.
  16918.  
  16919.           Proof Of Delivery:  This  security element provides proof and non
  16920.           repudiation of delivery.  It is a digital signature computed over
  16921.           the  received (possibly  encrypted)  message content  and various
  16922.           delivery envelope fields, as defined in the base standard.
  16923.  
  16924.  
  16925.           D.9.2   Algorithm selection
  16926.  
  16927.           This  clause makes  no  recommendation  as  to  hash  algorithms,
  16928.           asymmetric   encryption  algorithms,   or  symmetric   encryption
  16929.           algorithms.  The implementor  must select appropriate algorithms,
  16930.           based  on factors  such as  performance, cost, and  licensing and
  16931.           export restrictions.  A fairly complete list of algorithms can be
  16932.           found  in clause  7 (Security  Algorithms)  of Part  12 of  these
  16933.           Agreements.   In some cases,  the implementor  must also  specify
  16934.           certain algorithm-dependent information.  For example, when using
  16935.           the symmetric algorithm DES-CBC, the implementor must specify the
  16936.           padding mechanism used,  since this algorithm operates  on 8-byte
  16937.           input blocks.   Internet RFC 1115 defines such  padding rules for
  16938.           DES  and   RSA  in  various  modes,  and   these  mechanisms  are
  16939.           recommended unless security requirements dictate otherwise.  PKCS
  16940.           #1 (see  Bibliography, Annex  F) discusses  such matters  in more
  16941.           detail.
  16942.  
  16943.  
  16944.           D.9.3   Certificate management
  16945.  
  16946.           Management of public key certificates is beyond the scope of this
  16947.           recommended  practice.  X.509  provides a  generic authentication
  16948.           framework which uses the Directory to store certificates.  In the
  16949.           absence of  a ubiquitous  Directory, local means  may be  used to

  17044.  
  17045.           The purpose  of the  security functional  group is  to define  an
  17046.           approach  to the  provision  of  secure  messaging  with  Message
  17047.           Handling   systems  within   the   general  framework   of  these

  17051.           E.2    Message handling vulnerabilities
  17052.  
  17053.           The  message  handling  vulnerabilities (threats)  which  can  be
  17054.           protected   using  security  measures  are  defined  in  Annex  D
  17055.           (Security Threats) to Recommendation X.402 (1988):
  17056.  
  17057.                a)  Masquerading;
  17058.  
  17059.                b)  Message sequencing;
  17060.  
  17061.                c)  Modification of information;
  17062.  
  17063.                d)  Denial of service;
  17064.  
  17065.                e)  Repudiation;
  17066.  
  17067.                f)  Leakage of information.
  17068.  
  17069.           Other specific  threats exist if  there is a  failure to maintain
  17070.           information separation, which includes:
  17071.  
  17072.                a)  Manipulation;
  17073.  
  17074.                b)  Misrouting.
  17075.  
  17076.           Some of these  threats are defined in  ISO standard IS 7498,  OSI
  17077.           Reference  Model, Part 2: Security Architecture. The ISO standard
  17078.           also specifies  other threats, not  all of which  are relevant to
  17079.           message handling systems.
  17080.  
  17081.           Annex D to CCITT Recommendation X.402 (1988) also indicates which
  17082.           MHS  security  services  may  provide  protection  against   such
  17083.           threats.
  17084.  
  17085.           Some  threats  to  message  handling  systems  cannot  be  easily
  17086.           prevented,  merely detected,  others  are  not  appropriated  for

  17109.  
  17110.           E.3.1   Security policy
  17111.  
  17112.           A general  security policy  can be defined  as the  set of  laws,
  17113.           rules, and practices  that regulate how an  organization manages,
  17114.           protects,  and distributes sensitive information. Thus a security
  17115.           policy defines an organization's overall approach to security and
  17116.           must cover all security aspects.
  17117.  
  17118.           Security  within an  organization  is  not  only the  concern  of
  17119.           message handling service  and must be viewed in a more global and
  17120.           general  sense. The  wider  aspects of  a  security policy  would
  17121.           therefore include  personnel security  (such as  the vesting  and
  17122.           confidence placed in  staff), end-user access control,  physical,
  17123.           procedural  and  documentation   security.  These  Implementation
  17124.           Agreements however are only concerned with Electronic Information
  17125.           Security  (EIS),  specifically  in the  areas  of  communications
  17126.           (COMSEC) and computer (COMPUSEC) as applicable to standardization
  17127.           of  a secure  message handling  system operating  in a  store and
  17128.           forward environment.
  17129.  
  17130.  
  17131.           E.3.2   Security classes
  17132.  
  17133.           In the X.400  (1988) Recommendations, some threats  are countered
  17134.           by  EIS  measures,  these  measures  are  realized  by  providing
  17135.           security services and implemented using security elements.
  17136.  
  17137.           These Implementation Agreements groups together security features
  17138.           of a message  handling system defined by the  base standards into
  17139.           separate classes. A security class can be viewed as a  tool which
  17140.           can be used to implement a security policy, and is not a security
  17141.           policy in its own right but a component of a security policy.
  17142.  
  17143.           These  Implementation  Agreements  includes  a  set  of  security
  17144.           classes;  each class stipulates  a set of  mandatory and optional
  17145.           security  services. The security  classes are incremental subsets
  17146.           of the security features in the MHS Base Specifications:
  17147.  
  17148.                Security  Class  S0  only  requires  support  of  end-to-end
  17149.                security services  between UAs  (content integrity,  message
  17150.                origin  authentication, proof of delivery), and hence can be
  17151.                used to provide some protection  even in the case of transit
  17152.                through an intermediary MTS which may not be trusted.

  17167.  
  17168.           
  17169.  
  17170.                Security Class S1  additionally requires support and  use of
  17171.                secure access management  within the MTS so as  to allow the
  17172.                enforcement  of a  label-based  security  policy and  enable
  17173.                trusted interworking between security domains.
  17174.  
  17175.                Security Class S2  additionally requires support and  use of
  17176.                origin  authentication checks within  the MTS to  verify the
  17177.                origin of messages,  probes, and reports, thereby  making it
  17178.                possible to provide non-repudiation within the MTS.
  17179.  
  17180.           Mandatory  security services  within  a  security  class  can  be
  17181.           selected  by  the subscriber  or  user, either  on  a per-message
  17182.           basis, or for an agreed contractual period of time. It is a local
  17183.           issue to determine when a  mandatory security service is  offered
  17184.           for user selection or when it is permanently invoked.  Facilities
  17185.           and  mechanisms to support  the mandatory security  services must
  17186.           always be provided within the security class, which specifies the
  17187.           services as "mandatory."
  17188.  
  17189.  
  17190.           E.3.3   Dynamic behavior requirements
  17191.  
  17192.           The use of some security  services is always required for certain
  17193.           security  classes.  This  is specified  in  these  Implementation
  17194.           Agreements  by imposing additional dynamic requirements, to those
  17195.           specified  in the base standards, ensuring that the corresponding
  17196.           protocol elements are always present.
  17197.  
  17198.           Similarly,  use  of  some security  services  are  prohibited for
  17199.           certain   security   classes.   This   is   specified   in  these
  17200.           Implementation   Agreements   by  imposing   additional   dynamic
  17201.           requirements to those  specified in the base  standards, ensuring
  17202.           that the protocol elements are never present.
  17203.  
  17204.  
  17205.           E.3.4   Encryption techniques
  17206.  
  17207.           The secure messaging facilities defined in the base standards are
  17208.           provided using three basic security techniques, namely:
  17209.  
  17210.                a)  Symmetric encryption;
  17211.  
  17212.                b)  Asymmetric encryption;
  17213.  
  17214.                c)  Trusted functionality (i.e., COMPUSEC measures).
  17215.  
  17216.           The  base  standards permit  the  use  of  the techniques  on  an
  17217.           individual basis  to provided  security services  or they can  be
  17218.           combined  in support of  a security policy.  These Implementation
  17219.           Agreements  combine  the   techniques  in  order  to   provide  a
  17220.  
  17221.                                          250
  17222.  
  17223.  
  17224.  
  17225.  
  17226.  
  17227.  
  17228.  
  17229.  
  17230.

  17232.  
  17233.  
  17234.           
  17235.  
  17236.           comprehensive set of  security facilities, which are  intended to
  17237.           counter  various   combinations  of  the   vulnerabilities  of  a
  17238.           messaging service. In some cases the security services defined in
  17239.           the  base standards  can only  be  implemented using  one of  the
  17240.           techniques  above,  namely  asymmetric encryption.  However,  the
  17241.           actual technique employed  shall be dependent on  the algorithms,
  17242.           which shall be registered by a security authority for the domain.
  17243.  
  17244.           It  is  the  intention of  these  Implementation  Agreements that
  17245.           implementations will not be  restricted to asymmetric techniques.
  17246.           All  the mandatory  security services  can  be implemented  using
  17247.           trusted functionality in combination  with symmetric, asymmetric,
  17248.           or both encryption techniques.
  17249.  
  17250.           Although the  base standards defines the syntax  of an asymmetric
  17251.           token,  these Implementation  Agreements  takes into  account the
  17252.           ISO/CCITT MHS Implementors' Guide, which  permits the use of both
  17253.           asymmetric  and  symmetric  techniques for  both  the  signed and
  17254.           encrypted data.
  17255.  
  17256.           The  actual technique  employed depends  on  the algorithm  used.
  17257.           Algorithms are assumed to be  bilaterally agreed or registered by
  17258.           a registration authority.  However, the algorithm-identifier must
  17259.           be unique and unambiguously define the algorithm.
  17260.  
  17261.           It is recommended that a  conforming ASN.1 BIT STRING is normally
  17262.           used to contain the encrypted data  (as generated by use for  the
  17263.           ENCRYPTED macro), thereby ensuring insertion of padding zero bits
  17264.           which  may  be   necessary  for  correct  operation   of  certain
  17265.           algorithms. Alternatively,  the implementation  should take  such
  17266.           action explicitly.
  17267.  
  17268.           It is  recommended that,  in the absence  of any  requirement for
  17269.           support  of other specific algorithms, implementations shall as a
  17270.           default support  algorithms  identified in  CCITT X.509  (ISO/IEC
  17271.           9594-8). It is also strongly recommended that implementations are
  17272.           capable of using any encryption-based technique on a "plug-in" or
  17273.           modular basis.
  17274.  
  17275.           In  the  case  of  verification of  SIGNATUREs  (e.g.,  proof  of
  17276.           delivery,  MOAC, POAC,  or ROAC),  implementations  should assume
  17277.           that all relevant data present  in the subject message, probe, or
  17278.           report has been included in the signature.

  17323.           Content  Confidentiality may be  achieved by either  symmetric or

  17332.           and  is outside  the scope  of  these Implementation  Agreements.
  17333.           Mechanisms   to  support  Connection  Integrity  are  subject  to
  17334.           bilateral agreement between  peers. It should  be noted that  the
  17335.           integrity of a connection can be increased by use of RTSE.
  17336.  
  17337.           Content  Integrity is achieved  by computing a  content integrity
  17338.           check as a function of the entire message content. When symmetric
  17339.           techniques  are used  to compute  the  content integrity  check a
  17340.           secret  key  is required.  This  content  integrity  key  may  be
  17341.           confidentially  sent to the  message recipient using  the message
  17342.           argument confidentiality  security element  in the message  token
  17343.           (i.e., there  may be other keys or  parts of the key  not sent by
  17344.           the originator with  the message, but the key  management of such
  17345.           external  keys is  outside  the  scope  of  these  Implementation
  17346.           Agreements).   It  should  be  noted  that  placing  the  content
  17347.           integrity check in  the encrypted data of the  message token will
  17348.           provide additional protection against masquerade threats.
  17349.  
  17350.                NOTE  -  Content  Integrity can  also  provide  integrity of
  17351.                receipt and non-receipt notifications  (IPNs) and can assist

  17375.           End-to-end  (i.e., UA  to UA)  Message  Origin Authentication  is
  17376.           automatically provided by content integrity. Security classes  S2
  17377.           and S2a provide additional protection (i.e., of the  integrity of

  17382.           E.3.5.5   Non-Repudiation
  17383.  
  17384.           If asymmetric  techniques are used  for content integrity  it can
  17385.           also provide non-repudiation  of origin (UA  to UA) depending  on
  17386.           the level  of  trust  placed  in the  certificate.  If  symmetric
  17387.           techniques  are used,  content integrity  can  also provide  non-
  17388.           repudiation  of origin,  but only  by using  a trusted  notary to
  17389.           validate the content integrity and provide trusted key management
  17390.           facilities. A degree of non-repudication  can be provided by  the

  17392.  
  17393.                NOTE - It is assumed that an originating UA will ensure that
  17394.                delivery notification is requested when proof of delivery is

  17435.  
  17436.           An MTA performing distribution list expansion must create all the
  17437.           per-recipients fields for  the members of the  distribution list.
  17438.           It  may either  generate a  new token  for each DL  member (i.e.,
  17439.           using the recipient  name of that DL member)  or alternatively it
  17440.           may copy the  same token (i.e., containing the  recipient name of
  17441.           the DL itself) into the  per-recipient fields for each DL member.
  17442.           In the  former case,  the content-integrity-check  should not  be
  17443.           changed  if  it   is  to  be  used  to   provide  message  origin
  17444.           authentication.  Also in such  case, the DL  expansion point must
  17445.           have at least the same security  class as the originator and must
  17446.           have trusted functionality.  The choice of which  approach to use
  17447.           will therefore  need  to be  determined  in accordance  with  the
  17448.           security policy which may prohibit the use of distribution  lists
  17449.           altogether.

  17452.           E.3.5.8   Implications on redirection
  17453.  
  17454.           The Security Functional  Group has the effect of either requiring
  17455.           trust in  any redirection  facilities or  prohibiting the  use of
  17456.           redirection.  If the Redirection  facility is  to be  trusted, it
  17457.           must  be subject  to the  security policy  and obey  the security
  17458.           labels as defined  in the base standards. It  is recommended that
  17459.           the token  is not altered  on redirection (i.e., it  will contain
  17460.           the originally-specified recipient name).

  17465.           Interworking  between  implementations   conforming  to  Security
  17466.           Functional Groups  and 1984 systems is not  supported. The Double

  17468.  
  17469.  
  17470.           E.3.5.10  Implications for use of Directory
  17471.  
  17472.           The X.400 security services use of the directory service does not
  17473.           require  a  trusted  directory because  the  information  that is
  17474.           retrieved is certified and can be validated  independently of the
  17475.           directory.
  17476.  
  17477.           Other   threats   (e.g.,   malicious  corruption   of   directory
  17478.           information) may arise  from the  broader use  of the  directory,
  17479.           however these are outside of the scope of the X.400 base standard
  17480.           and this Implementors Agreement.
  17481.  
  17482.           Work  continues within  CCITT  and ISO  to  improve the  security

  17504.           either  require that any conversion facilities are highly trusted
  17505.           to  regenerate  the  appropriate security  elements  (notably the
  17506.           content integrity check) or prohibit the use of conversion within
  17507.           the MTS altogether. In particular, it should be noted that use of
  17508.           conversion facilities will  invalidate any origin  authentication
  17509.           based on the original content.

  17511.  
  17512.           E.3.5.12  Accountability
  17513.

  17515.           of users, then subsequent records being kept on the actions taken
  17516.           by users. Therefore,  accountability depends on all  the relevant
  17517.           information being properly stored or recorded.
  17518.  
  17519.           Accountability features provided by domains (or MTAs) are subject
  17520.           to   bilateral  agreement  between  domains  (or  MTAs)  and  may
  17521.           optionally  provide   non-repudiation  services.   Accountability
  17522.           features  include pervasive  mechanisms  such as  security  logs,
  17523.           audit trails and archives, or they may be mechanisms supported by
  17524.           protocol.  Protocols to support accountability will be subject to

  17644.           E.4.2   Technical implications
  17645.  
  17646.           The technical implications for security class S0 are:
  17647.  
  17648.                a)  It is necessary to provide mechanisms in a UA  which can
  17649.                generate the  signed,  signature  and  encrypted  macros  on
  17650.                message submission; and,
  17651.  
  17652.                b)  It is necessary to provide  mechanisms in a UA which can

  17658.  
  17659.  
  17660.           E.5.1   Rationale
  17661.  
  17662.           The S1  security class  is a superset  of security  class S0  and
  17663.           introduces the basic  requirement for security  functionality not
  17664.           only within the  MTS-User but also within the  MTS. This security
  17665.           functionality  within  the   MTS  is  designed  to   support  the
  17666.           enforcement of a  security policy within a security  domain. As a
  17667.           consequence, S1 enables trusted routing to be implemented.
  17668.  
  17669.                NOTE - The  level of trust in  the route will depend  on the
  17670.                level of trust in the security label and security context.

  17707.                MS-Bind);
  17708.  
  17709.                e)  It  is necessary to  support message security  labelling
  17710.                (the  level of assurance  is subject to  individual security
  17711.                domain requirements);
  17712.  
  17713.                f)     It  is  necessary  that  reliable  access  is  always
  17714.                supported;
  17715.  
  17716.                g)  It is necessary for  the MTAs to check the existence  of
  17717.                the  security elements  which  are  classified  as  "dynamic
  17718.                mandatory";
  17719.  
  17720.                h)  It is necessary  to provide a trusted connection between

  17727.  
  17728.           E.6.1   Rationale
  17729.  
  17730.           Security Class S2 is a superset of Security Class S1. It enhances
  17731.           the facilities of  the MTAs in order to check  the origination of
  17732.           messages,  probes, and  reports  within the  MTS  and to  provide
  17733.           enhanced integrity checks on the security label while in the MTS.
  17734.           The  extra security services provided by  this security class can
  17735.           help to provide trusted routing within an MTS.
  17736.  
  17737.           Additionally, it is possible to provide non-repudiation within an
  17738.           MTS.
  17739.  
  17740.  
  17741.           E.6.2   Technical implications
  17742.  
  17743.           The extra  security services specified  by Security Class  S2 use
  17744.           asymmetric techniques exclusively.
  17745.  
  17746.           The technical implications are as in Security Class S1, plus:

  17760.  
  17761.  
  17762.           
  17763.  
  17764.                a)  It is necessary to  provide mechanisms in an MTA and  UA
  17765.                that can process the signed macro of certificates;
  17766.  
  17767.                b)   The constraint  that the  option of  supporting Content
  17768.                Confidentiality cannot be  allowed when  the message  origin
  17769.                authentication  check  (MOAC)  is   used  to  provide   non-
  17770.                repudiation   services.   Under   this   condition   Content
  17771.                Confidentiality is  not supported. If  the MOAC is  not used
  17772.                for this  purpose, Content Confidentiality  can be supported
  17773.                as an optional security service;
  17774.  
  17775.                c)  It is necessary to provide mechanisms in a MTA which can
  17776.                generate  and  process  the signature  macro  of  a message,
  17777.                probe,  and  report  authentication  check  (MOAC, POAC  and
  17778.                ROAC);
  17779.  
  17780.                d)  It  is necessary to provide  mechanisms in a UA  and MTA
  17781.                that  can interface with  an X.500 directory  supporting the
  17782.                Authentication Framework as  defined in X.509/ISO 9594-8  or
  17783.                can distrubute public  keys by other trusted means  which is
  17784.                compliant with X.509;
  17785.  
  17786.                e)  It is necessary to provide a trusted means of generating
  17787.                certificates;
  17788.  
  17789.                f)  It is  necessary to provide mechanisms in  the MTA which
  17790.                can process a proof  of submission request and  generate the
  17791.                proof of submission signature;
  17792.  
  17793.                g)  It is  necessary to provide a mechanism in  an MTA which
  17794.                will generate ROAC signatures with reports;
  17795.  
  17796.                h)   Connection  confidentiality is  only  provided by  this
  17797.                security class when  the message-origin-authentication-check
  17798.                is  computed using clear  content to provide non-repudiation
  17799.                of  origin  security   service  (i.e.,  non-repudiation   is
  17800.                provided only on the clear content of the message);
  17801.  
  17802.                i)    The   irrevocable  proof  required  to   provide  non-
  17803.                repudiation within the MTS is  achieved by the management of
  17804.                asymmetric keys. The explicit  definition of asymmetric  key
  17805.                management  is  outside  the  scope  of  these  Implementors

  17831.  
  17832.  
  17833.           E.7.1   Rationale
  17834.  
  17835.           These security  class variants are  supersets of S0, S1,  and S2,
  17836.           adding   the  requirement  for   support  of  end-to-end  content
  17837.           confidentiality. The rationale for these variants is to avoid the
  17838.           implementation   cost   and  processing   overhead   involved  in
  17839.           encrypting the entire message content unless there is  a definite
  17840.           requirement.  It is  also  possible  to  protect  the  encryption
  17841.           techniques  and  mechanisms (i.e.,  algorithms, key  lengths, key
  17842.           versions, etc.) by Secure Access Management.

  17848.           variants  are the  same  as those  for the  corresponding primary
  17849.           security class, plus:
  17850.  
  17851.                a)  It  is necessary to provide mechanisms in a UA which can
  17852.                use the encrypted macros to encrypt and  decrypt the message
  17853.                content.

  17968.  
  17969.           Several  additional  requirements  for Message  Handling  Systems
  17970.           (MHS) in the U.S. Department of Defense (DoD) are currently being
  17971.           investigated by the Data Communications Protocol Standards (DCPS)
  17972.           Technical Management Panel (DTMP).  This annex  describes the DoD
  17973.           Standardized Profile(s)  (DSP)  that  are  required  for  Defense
  17974.           Message System (DMS) use.
  17975.  
  17976.           Two multipart DoD profiles are currently defined, namely:
  17977.  
  17978.                -    DSP   AMH1n(D)  -  Information  Technology   -  Defense
  17979.                Standardized Profiles AMH1n(D) -  Message Handling Systems -
  17980.                Common DoD Messaging
  17981.  
  17982.                -    DSP   AMH2n(D)  -  Information  Technology   -  Defense
  17983.                Standardized Profiles AMH1n(D) - Message Handling  Systems -
  17984.                Military Messaging
  17985.  
  17986.           These  profiles will  be  published as  part of  the MIL-STD-2045
  17987.           series.   The  AMH1n(D) profile  consists of  a DoD delta  to the
  17988.           AMH1n ISP.   AMH2n(D) is a  standalone profile of a  new military
  17989.           messaging  content type  (P772) based  on the  IPM content  type.
  17990.           These extensions  support military-unique functionality  required
  17991.           by the DMS.
  17992.
