一种基于组控制器的组播密钥管理方案

A Multicast Key Management Scheme Based on Group Controller

日益涌现的组播应用对安全提出了特殊要求。针对IPSec协议在组播环境中存在的问题,文章提出一种基于组控制器的一对多组密钥管理方案;将组密钥与源鉴别密钥捆绑在一起,很好地解决了组播源鉴别问题。分析结果表明方案有效控制了组密钥更新对系统性能的影响。

Increasingly multicast applications pose special requirement on security.Focusing on key issues of IPSec protocol applied in multicast,this paper proposes a one-to-many multicast key management scheme based on group controller,which binds a group key with individual authentication keys to provide single source authentication of IPSec for multicast.The end analysis results show that this scheme well controls the effect of group key update on system performance.
