摘要

在多媒体会议系统中，保密性的需要变得越来越重要。这个目标可以通过加密来实现。在实时视频处理系统中，有对部分数据加密的特殊需求。研究了现有的方法及其不足。我们提出了一种视频数据部分加密的新方法，它允许几乎每个粒度的安全级别。它可以应用于所有基于jpeg的视频压缩方法。

A scalable security architecture for multimedia communication standards

In multimedia conferencing systems the need for confidentiality gains in importance. This goal can be achieved by encryption. In real-time video processing systems there is a special need for partial data encryption. Existing methods and their weaknesses are investigated. We present a new approach for partial encryption of video data, which allows a security level of nearly every granularity. It can be applied to all JPEG-based video compression methods.
