Securitymechanisms for Multimedia-Data with the Example MPEG-I-Video

The digital Studio-TV-Signal, decribed by the CCIR Recommendation 601 has a data rate of 166 Mbit/s. None of the existing digital media has the possibility of working with this data rate and ensuring at the same time security mechanisms like 'Confidentiality' (using encryption) or 'Integrity' using (Hash-sums). The new methods, descibed by this paper, are specialy designed to ensure these security mechnisms for the high-volume video-signal of the ISO Standard 11172 (MPEG-I) [ISO92] for communication.
