基于移动代理的多播水印协议

Multicast watermarking protocol based on mobile agents

提出1个基于移动代理的位置无关的多播水印协议(MAMWP),使用移动代理来实现每个组成员接收到的是不同的数据流拷贝.该协议可以解决多播和指纹的矛盾,实现多播系统中的盗版源跟踪或泄密者识别.MAMWP不依赖于中间实体的安全性和计算能力,在实现上可以独立于现有的任何多播体系,有很好的扩展性,并且支持动态的组成员身份.MAMWP可作为多播安全系统的一个可选组成部分.

It is presented a location-independent multicast watermarking protocol based on mobile agents (MAMWP),which uses mobile agents to give every member a unique watermarked data copy.MAMWP can coordinate the performance of multicasting and the uniqueness of fingerprinting,provide traitor tracing or leaker identification.MAMWP does not depend on the security and computing performance of the intermediate entity,can be built on top of any existing multicast architecture,has good scalability and supports dynamic group membership.MAMWP can be selected as an optional component of secure multicast system if the traitor tracing or leaker identification is needed.
