摘要：  组播是面向群组接收者的首选网络通信技术,但缺乏安全机制限制了组播在各种网络业务中的广泛应用。而组密钥管理是安全组播的核心问题之一。在对安全组播密钥的管理进行深入研究后,结合门限函数和单向函数提出了一种在维持低的通信代价基础上,不仅可以有效的减少组管理器的密钥存储量,而且能降低同谋破解概率的组密钥管理方案。

Abstract: Multicast is the current prime network technique focusing on the group receivers,but the absence of security mechanism has limited its application in various network services.Group key management is one of the kernel problems in secure multicast.A group key management scheme for secure multicast was proposed,which can not only effectively reduce the key numbers of group controller,but also detract the probability of alliance attack.

Key words: secure multicast, key management, threshold function, logical key tree
