摘要
为解决目前的自愈组密钥分配方案只能支持m个会话的问题,提出了一种有效的具有撤销能力的、δ-自愈组密钥分配方案。通过在每个会话期更新组成员节点的私钥和进行部分撤销,方案可以支持无限次会话。安全性和性能分析与仿真结果表明,方案在解决了生命期延长问题的前提下,保证了方案的安全性,降低了存储开销和通信开销。
In order to resolve the problem that the current self-healing group key distribution schemes are only able to support m sessions,an efficient δ-self-healing group key distribution scheme with revocation capability is proposed.The proposed scheme is capable of supporting infinite sessions by updating the private key of the group member nodes during each session and performing a partial revocation.Security and performance analysis and simulation results show that the proposed scheme has settled the life-time extension problem yet still achieved security property and lowered the storage and communication costs.
