分布式安全组播体系结构的实现

随着因特网不断商业化和用户数量的急剧增加，组播通信中的安全问题受到研究人员的日益关注。许多研究机构提出了解决这些安全问题的体系结构。文章通过分析组播的安全问题和安全服务，给出了设计体系结构中需要注意的问题。在分析这些体系结构的基础上，提出了具有安全策略的DSMA(Dist Iibuted Secure Mumcast Architecture)体系结构，它对Iolus单点故障进行了解决。最后给出了DSMA的实现方案。

Implementation of A Distributed Secure Multicast Architecture

With the commercialization of Internet and increase of users, researchers pay more and more attention to the issues of secure multicast communication. Many organizations had put forward architectures resolving these issues.By analyzing the issues of secure multicast and secure services, this paper states problems of secure multicast architecture which need to be noticed. On the basis of analyzing those architectures, this paper bring forward the Distributed Secure Multicast Architecture with a secure policy, Which gives a solution of single point of failure for Iolus. At last this paper gives an implementation about DSMA.
