摘　　要：无线自组织网络是一种分布式无中心的多跳网络,具有网络拓扑结构不断变化、网络自治、易受攻击等特点,因而传统的密钥管理体制变得不再适合,而秘密共享体制则为自组织网络的密钥管理提供了一种有效途径。前向安全的密钥管理协议是在秘密共享基础上,结合前向安全的思想和基于标识加密公钥算法,支持共享密钥和密钥份额随时间周期更新的密钥管理方案。前向安全的密钥管理协议支持成员动态变化,适合无线自组织网络的密钥管理,相对于传统的密钥管理方式,其安全性有很大提高。The wireless Ad-hoc network is a distributed multi-hopping network（without center）, and its topology structure is constantly changing, and its network autonomous and vulnerable to attack. So, traditional key management system is not suitable for this network. Secret-sharing system provides an efficient method for key management in Ad-hoc network. The forward secure key management protocol, based on secret sharing scheme and is combination with forward security and Identity-based encryption, supports the secure key management scheme with that shared key and key shares updating with time period. This forward secure key management protocol supports the members dynamically changing, and thus is applicable to wireless Ad-hoc network. And experiment indicates that its security is much higher than that of traditional key management mode.
