一种在应用层通过信息隐藏实现的安全组播方案

An Approach to Security Multicast on Application Layer

根据多媒体组播应用程序的特点 ,结合数据隐藏的研究成果 ,提出了一种在应用层发放和管理密钥 ,并依靠密钥嵌入媒体流的方法来实现多媒体组播应用中的访问控制。

To solve the problem of control access to multimedia multicast, encrypting the mediastream data is a popular approach. With analyzing the characteristics of media data and the technique of information hiding algorithm, an approach to achieve this aim by data embedding is proposed, in which the key is transmitted and managed on application layer, and is embedded into media stream.
