基于零知识的分布式群组密钥管理方案

New distributed group key management scheme based on zero-knowledge set

在分析现有群组密钥交换协议的基础上,提出了一种基于零知识的分布式群组密钥管理方案。该方案实现了零知识性和分层结构的有机结合,对组控制器的密钥存储量、加密计算量、单播和广播次数等的分析结果表明,该方案提高了群组通信的效率,并具有良好的可扩展性,可应用于网络秘密会议等多种群组通信环境。

On the basis of analyzing existed schemes,a distributed group key management scheme based on zero-knowledge set is proposed.This scheme achieves the integration of zero-knowledge set and hierarchy,and it is shown that the efficiency of communication is improved so much by the analyses of the storage,the calculation,the time of broadcast and the one-to-one.So it possesses better scalability than other schemes,can be applied to actual internet environment anonymity situation,such as secret network meeting.
