MPEG-FAQ 4.0:

What is "SECMPEG" ?

  SECMPEG is first a newly defined stream, that ensures the service
  of confidentiality and integrity for a MPEG-I-video-stream. 'Cause
  of the amount of multimedia-data it is NOT possible to use the same
  crypto- or checking-techniques for multimedia-data then for normal
  files or streams.



  Therefore we defined a new stream, containing additional security
  information. We tested and filtered the MPEG-I-stream to ensure that
  only important and relevant data is encrypted or checked. The newly
  desinged methods are not proofed but quite good tested. We can't be
  sure so far, if these method really do what they are designed for.



  It is second a tool, that can insert and delete the confidentiality
  and integrity data into/from a MPEG-I-stream.

  If you get any results to proof our methods, we hope to here from you !

  More information is available from te authors, like some PostScript-
  files, pictures and graphs.


  Where is it ?

  It will stored on our ftp-server in the next days (probably there):

        URL= ftp://ftp.cs.tu-berlin.de/pub/msdos/dos/graphics/secmpeg.zip
             (the DOS-Version)

  or probably in the unix-directory somewhere.


  How does it compile ?

  The program already compiles under

  - SunOS 4.1.x            using cc or gcc
  - SunOS 5.0              using cc or gcc
  - Solaris 2.1            using cc or gcc
  - INTERACTIVE Unix 2.2.1 using cc or gcc
  - Linux                  using gcc
  - MS-DOS                 using gcc or Borland C 2.0 (tcc),
                           the dos-port shoulb be included as
                           executable in the archive

  You need a compiler, that understands ANSI-C so far, but the rest is
  straight forward C, so it should compile nearly everywhere.
