| 摘 要： | 密钥管理是解决移动Ad hoc网络中安全通信问题的重要环节。在分析网络特点的基础上，提出了一种基于DiffieHellman协议的动态混合密钥管理策略(DHKM)。通过网络分簇，将多个簇首节点一起作为权威机构执行管理功能,采用DiffieHellman交换，并利用成员过滤函数维护密钥，适应网络拓扑的动态变化。结果表明，DHKM保证了密钥的完整性和机密性，并有效减少了密钥更新对网络性能的影响。

| Abstract: | Secure communication is very important in Ad hoc networks and key management is one of most eminent things in security quality. This paper presented a cluster based dynamic hybrid key management(DHKM) solution, based on the theory of Diffie Hellman. After dynamicallyclustering the mobile nodes distributed randomly, these clusterheads jointly executed administrative functionsrelying on Diffie Hellmanprotocol. Utilized member filter function to maintain key management, which accommodated to topological dynamic change.It concludes that DHKMmodel ensuresintegrity,confidentialityand adapts to the special requirements for frequent key refresh. |
