摘　　要：Ad hoc网络特性要求所采用的切换方案必须是轻量的。将中国剩余定理和分簇的思想相结合,为Ad hoc网络提出了一种新的门限签名方案,在此基础上,提出一种轻量级分簇切换方案。通过分簇的门限签名保证了簇对话密钥的真实性,设计了在簇内和簇间两种情况下的切换操作流程,实现了快速安全的切换。该方案能够灵活适应Ad hoc网络动态拓扑性,适用于各种规模的网络。数学证明和安全性分析表明,该方案具有很高的安全性,并具有抗共谋攻击的能力。The characteristics of Ad hoc networks require that the security approaches in Ad hoc networks must be light- weight. A new threshold signature scheme basd on the Chinese Remainder Theorem and clustering was presented for Ad hoc networks, and then a lightweight handover scheme was presented. The threshold signature scheme based on the cluster structure can guarantee the reality of cluster session key. The process of inter-cluster handover and intra-cluster handover can realize security handover quickly. The scheme can be used in different scale networks and can meet the dynamic topology of the Ad hoc networks. The mathematical proof and analysis show that the scheme is secure and have the ability to resist collusion attack.
