Research and Analysis of Secure Multicast Architecture based on IP Security
基于IP Security的安全多播体系结构的研究与分析

On the base of analyzing the security problem of the current IP multicast research and application,this paper introduces an architecture of secure IP multicast based on IPSec,identifies the basic components and functions and specifies how these components interact with each other and the surrounding systems. Especially,the group key management mechanism is analyzed and compared in detail.This architecture takes advantage of the IPSec mechanism and expands it.Therefore,the simplicity,flexibility,and ease of incorporation within existing systems are its main features.
