| 摘 要： | 针对GDH(group diffie-hellman)方案中节点可能成为系统的瓶颈以及计算复杂度、通信代价和存储复杂度远高于某些集中式方案等缺陷,提出并实现了一种基于优化GDH协商的高效安全的动态群组密钥管理方案,并对其安全性进行了证明。通过对计算量和通信量进行分析比较表明,优化GDH协商协议具有很大的优势,并且能够快速产生或更新组密钥,具有很强的实用性。

| Abstract: | There are some defects in GDH(group diffie-hellman) scheme,such as the node that may become the bottleneck of the system,and the computational complexity,cost of communications and storage complexity that are much higher than some centralized group key management program.An efficient and secure dynamic group key management scheme based on optimized GDH is proposed and implemented and its security is proven.The optimized GDH consensus agreement has great advantage than GDH by comparing and analysing the volu... |
