基于CBT组播路由协议的组密钥管理协议分析与改进

摘要：

In RFC1949,A. Ballardie proposed a method of scalable multicast key distribution based on the Core Based Tree multicast protocol fitting for wide-area IP multicasting. This paper analyses the method deeply,points out that the model can't resist the key compromise of a single member effectively,and proposes two kinds of improvement. One is the distributed generating and distributing group data encryption key,the other one is partitioning the group into subgroups. These improvements can increase the security and lifetime of the group key,and decrease the loss of compromise of a single group key encryption key.
