| 摘 要： | 安全组播是组播技术走向实用化必须解决的问题。在组成员动态变化时,设计一个高效的密钥管理方案是安全组播研究的主要问题。提出了一种基于新型混合树模型的组播密钥更新方案。该方案将GC的存储开销减小为4,同时,在成员加入或离开组时,由密钥更新引起的通信开销与nm保持对数关系(n为组成员数,m为每一族包含的成员数)。

| Abstract: | Secure multicast is a key issue to be solved that multicast technology can be widely deployed.When group members join or leave dynamically,the main research for secure multicast is how to design an efficient key management scheme.This paper discusses a novel rekeying scheme for secure multicast based on LKH hybrid tree model.The proposed scheme reduces the key storage requirement of the group controller to four.Furthermore,the key update communication induced by member joining/leaving is logarithmic with nm,where n denotes the number of group members,and m is the size of a cluster. |
