摘　　要：ad hoc网络作为一种无线移动网络正成为网络研究中的热点之一。针对移动ad hoc网络的特性和对目前已有的移动ad hoc网络密钥管理方案的分析,提出了一种基于信任图和门限密码技术的全分布、自组织的移动ad hoc网络密钥管理新方案。该方案允许节点发布公钥证书并且通过证书链实施认证,有效地解决了网络节点之间的信任,同时又阻止恶意节点发布错误公钥证书欺骗认证服务。该方案具有较高的可靠性、扩展性和安全性,适用于大规模移动ad hoc网络。The ad hoc networks is turning to he a hotspot of research. For mobile ad hoc network characteristics and available mobile ad hoc network analysis of key management scheme currently, proposed a fully distribution, self- organizing new key management scheme for mobile ad hoc networks based on trust graphs and threshold cryptography. It permits nodes to issue public key certificates and to perform authentication via certificates＇ chains. It is an effective solution to the trust between network nodes, in which prevent malicious nodes from issuing false certification to deceive certification services. It has higher reliabilty, extensibility ,security, applies to the large scale mobile ad hoc network.
