摘　　要：自组网以灵活的组网特性正越来越受到人们的关注。然而,这种灵活特性又给自组网的安全性带来了巨大的挑战。密钥管理是实现该类网络安全的重要环节。首先,基于补图团的着色思想提出了分布式分簇算法,在此基础上,结合TGDH(Tree-Based Group D iffie-Hellman)算法给出了一种混合密钥管理方案。理论分析此方案具有良好的性能。Ad Hoc networks have attracted more and more attention recently due to its character of self-organization. However, this character brings big challenges to it in the field of security. Key management is one of most importance things in security service. A new distributed coloring-based clustering method was introduced. Based on it, a hybrid key management scheme using the TGDH algorithm was proposed. The good performance of this strategy was proved by theoretical analysis.
