一种新的应用密钥图的安全组播密钥管理方案

该文讨论了安全组播通信中密钥管理问题。借鉴多目标优化问题中的解法,提出了一种基于点覆盖求解算法的密钥分配机制的方案,该方案采用全局优化的自适应概率搜索机制,大大提高了算法的效率,适用于处理大规模组播群组成员动态变化的应用。

A Novel Key Management Scheme for Secure Multicast Using Key Graphs

The paper studied the key management problem in a secure multicast group with a single sender and multiple receivers. We show how to minimize the number of keys to be stored by the group controller. An explicit design algorithm is also presented.
