A Secure IP Multicast Protocol Suite : Architecture and Implementation

1.引言 随着Internet的普及和商业化应用的增长,越来越多的应用需要多播服务,如大规模信息传播服务、实时视频会议、分布交互式模拟、协同工作等等.为了保护多播消息的内容,需要建立多播安全基础设施.

Security Protocols are a key component of a secure multicast infrastructure. Securing IP multicast communication is a complex task that involves many aspects. Consequently, a secure IP multicast protocol suite must have a number of components that address different aspects of the problem[5]. This paper prsents a layered secure multicast protocol suite consisting of five protocols, and describes an implementing model of the protocol suite. The design goal of the protocol suite is to support the secure group model and the lifecycle model of secure groups. The concept of these models is introduced by [6] and [7].
