摘　　要：提出了一个分布式的基于品质度量的分层密钥优化管理机制。该机制通过动态选择高品质的节点作为PKG来增强移动Ad Hoc网络的安全性,并将网络生存时间最大化。节点的选择可以归结为随机(restless bandit)问题,并且将密钥更新过程分为在线和离线两个部分,从而降低了计算复杂性。仿真结果表明,该机制可增强网络的安全性和将网络生存时间最大化,非常适合移动自组网的应用要求。A distributed optimized hierarchical key management scheme based on quality measurement in which nodes can get their keys updated from optimally selected nodes. The key management problem is formulated as a stochastic system,and the proposed scheme can select the best nodes from all available ones based on their security conditions. Simulation results show that the network compromising probability in the proposed scheme can be decreased.
