摘　　要：为解决传统无线Ad hoc网络邻居匿名认证方案容侵性不佳以及难以锁定恶意节点身份的问题,提出一种基于双线性对的无线Ad hoc网络可追踪邻居匿名认证方案。采用基于身份的公钥系统,节点随机选择私钥空间中的数作为临时私钥,与身份映射空间的节点公钥以及一个公开的生成元模相乘得到临时公钥,利用双线性映射的性质协商会话密钥并实现匿名认证。通过在随机预言机模型下的形式化分析,表明本方案在BCDH问题难解的假设下可对抗攻击者的伪装行为,同时利用认证过程中交互的临时公钥可有效锁定恶意节点真实身份。To improve the disadvantage in traditional anonymous authentication schemes for wireless ad hoe networks which are vulnerable to nodes intrusion and unable to trace malicious nodes, a pairing-based traceable neighborhood anonymous authentication scheme was proposed. Using an ID-based public key system, the authenticating node chooses a random number from the private key space as its temper private key, and then multiplies this temper private key with his ID-based public key and an all-known generator respectively to create its temper public key. Using such temper keys pair, the node can establish anonymous authentication with its neighbors in a secure and efficient way. By formally analyzing this scheme under random oracle model, it is shown that this scheme can efficiently resist the impersonation attacks as long as the BCDH problem is hard and the hostile nodes can be traced through their temper public keys by the network manager.
