摘　　要：针对无线移动Ad Hoc网络中匿名认证问题,提出一种新的基于身份的匿名认证机制。通过节点匿名身份集以及身份签名算法设计匿名认证协议,实现完全匿名认证。通过秘密陷门机制派生匿名身份集,减少匿名撤销时的通信开销。性能分析与仿真结果表明,该机制的协议通信开销以及匿名撤销效率优于现有匿名认证机制,适合在移动Ad Hoc网络中应用。Aimed at the anonymous authentication problem in mobile Ad Hoc networks, a new identity based anonymous authentication scheme is proposed. Based on the node＇s pseudonym set and identity based signature, a full anonymous authentication scheme is proposed. Meanwhile, based on the secret trapdoor scheme, the communication overhead is reduced at the pseudonym revocation process. The analysis and experimentation show that the communication overhead is lower and successful rate of pseu- donym revocation are better than the existing schemes. The scheme is more suitable for the mobile Ad Hoe networks.
