| 摘 要： | 缺乏安全机制限制了组播在各种网络业务中的应用.组播密钥管理通过为组播成员生成、发送和更新组密钥来满足加密认证等安全需求.组播密钥管理方案的设计,除了要满足基本的安全需求,还要兼顾可扩展性、健壮性、可靠性等多方面因素.分析了组播密钥管理所面临的问题,并通过对已有的几种组播密钥树方案的介绍,探讨和总结了组播密钥管理的研究现状和发展趋势.

| Abstract: | The absence of security mechanism has limited the use of multicast. Key management for multicast is used for group members in one multicast session to generate, refresh and transfer keys which are used for encryption and authentication. In addition to the maintenance of keys, issues about scalability, reliability and robustness should be carefully considered. In this paper, the existing problems in key management for multicast are analyzed, and some typical schemes are reviewed. |
