摘　　要：针对设计高效的分布式密钥协商方案是动态对等群组组播通信的难点,提出了一个新的基于Merkle身份树的密钥协商方案,并具体地分析了子组之间的通信过程,以及组成员动态变化时密钥的更新过程。结果表明该方案在降低计算和通信代价方面取得了较好的效果。Designing efficient distributive key agreement scheme was a difficult problem in multicast communication of dynamic peer groups. This paper proposed a new key agreement scheme for muhicast groups based on Merkle identity tree . Then analyzed the procedures of secret communications between subgroups and updating of group keys with the dynamic change of group members in detail. The analysis shows that the new scheme is efficient in computation and communication.
