摘要
针对Ad hoc网络的特点,提出了一种基于分簇的分布式密钥管理方案。该方案在簇内采用贡献份额的思想,由部署信息直接派生节点间的端端密钥;在簇间,由节点协商产生共享密钥。经分析表明,该方案避免了单点失效,对拓扑结构动态变化的网络适应性强,比传统方案更高效、更安全。
According to the characteristics of ad hoc networks,a distributed key management scheme for ad hoc networks was proposed.In the cluster,the peer to peer keys are directly generated by the contribution of deployment information,while between the clusters,the keys are generated by cooperation.The proposed scheme avoids single point of failure and is highly adaptive to frequent topology changes.It is analyzed that this scheme is more efficient and security than traditional scheme.
