摘　　要：已提出的Ad hoc网络密钥管理方案中,需要多个节点承担服务节点的角色,这与Ad hoc网络的无中心、节点对等、自组织等特性相违背,健壮性差,且公私钥对及证书生成时通信量大。提出一种新的自组织的Adhoc网络密钥管理方案,它将零知识证明应用于证书的认证过程,使得节点公私钥对及证书完全由节点自己生成,认证工作亦无须服务节点的参与,由认证双方参与即可。实验表明,此方案通信量低、可靠性高、健壮性强。The proposed public-key managements of Ad hoc networks must take many nodes as service nodes,which run counter to the characters of Ad hoc networks,such as self-organized and centerless.They also take much traffic to create public-private key pairs and certificates,and they are poor in robustness.This paper proposed a novel fully self-organized public-key management system that took zero knowledge proofs into the process of certification and allowed users to generate their public-private key pairs,to issue certificates,and to perform authentication regardless of the network partitions and without any certralized services.The protocol analysis study and simulations prove that the public-key management system has low traffic,high reliability and robustness.
