摘　　要：在Ad hoc网络中,组密钥管理是安全核心问题.针对Ad hoc网络无基础设施和网络拓扑结构易变化的特点,提出了一个可认证的动态群组密钥协商方案.该方案基于身份密码学体制采用门限机制技术,在系统初始化完成以后,组密钥的生成和维护不需要可信任的第三方,而是由系统中的节点来共同完成.分析表明,该方案就计算复杂度和通信复杂度而言都是高效的,能够满足Ad hoc网络动态组密钥管理的安全要求.In mobile Ad hoc networks, group key management is one of the most important secure problems. In order to realize secure group key agreement protocols in mobile Ad hoc networks which have no infrastructure, a scheme consisting of identity-based cryptograph and threshold mechanism was proposed. With the protocols and some proper parameters, every node in the Ad hoc networks takes part in computing the group key without a trusted third party. The analysis resuhs show that the proposed protocol is efficient in terms of both computation and communication complexity, and can satisfy the security requirements group key management in mobile Ad hoe networks.
