新兴的计算机网络技术保证了实时提供分布式多媒体。实时视频作为分布式多媒体应用的重要组成部分，其安全性日益成为计算机网络界关注的主要问题之一。本研究提出了Aegis，一个安全系统的运动图像专家组（MPEG）压缩视频传输。Aegis利用MPEG视频压缩算法的概念，以提供有效和高效的安全机制。一个原型实现被用来评估其有效性，在安全的视频传输。Aegis在异步传输模式（ATM）技术环境中的仿真结果也被提出，以证明其性能相比，传统的加密/解密方法。
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.
