Abstract

Emerging computer network technologies promise to provide distributed multimedia in real-time. Security of real-time video, an important component of distributed multimedia applications, is increasingly becoming one of the major concerns of the computer networking community. This study presents Aegis, a security system for Motion Picture Experts Group (MPEG) compressed video transmissions. Aegis utilizes the concepts of the MPEG video compression algorithm in order to provide an effective and efficient security mechanism. A prototype implementation is used to evaluate its effectiveness in securing video transmissions. Simulation results of Aegis in an asynchronous transfer mode (ATM) technology environment are also presented in order to demonstrate its performance in comparison to traditional encryption/decryption methods
