摘　　要：Ad hoc网络的密钥管理技术是影响Ad hoc网络发展的重要因素,本文对Ad hoc现存密钥管理技术进行了研究.在基于身份密码系统的基础上,提出了UCKG(User Contributed Key Generation)密钥生成策略及分布式密钥管理协议,克服了身份密码系统存在PGC欺骗以及需要安全信道分发密钥的缺陷.对UCKG分布式密钥管理协议使用NS工具进行了性能仿真,当网络具有较好的连通性时,提出的密钥管理协议具有较好的性能.Key management protocol is a key problem for Ad hoe network security. In this paper, we introduced a user contributed key generation strategy （UCKG） based on the identity based cryptography （IBC）. Compared to IBC key generation strategy, UCKG has no PGC-cheating problem and no requirement of secure channel for key distribution. We also proposed a distributed key management protocol for UCKG and simulated it with NS-2. The simulation results show that while the network has the good connectivity, the distributed key management protocol has good performance.
