摘要
针对Mobile Ad Hoc网络提出了一个改进的匿名认证协议,主要目的是提供一个隐藏通信节点真实身份的机制,提高对恶意攻击的抵御能力。端到端的匿名认证进行基于对称和非对称密钥加密的三次握手,在成功完成认证过程后,安全的复合匿名数据通道才能被建立。匿名由拥有随机选择伪身份的用户来担保,网络节点公开认证并且独立于用户的伪身份。文章通过一个网络模型介绍了该协议的执行过程,并对其安全性进行了简要分析。
A new anonymous authentication protocol is proposed For Mobile Ad Hoc Networks, the main purpose is to provide the true identity of a hidden node communication mechanism and to improve resilience against malicious attacks. The end-to-end anonymous authentication is conducted in three-pass handshake based on an asymmetric and symmetric key cryptography. After successfully finished authentication phase secure and multiple anonymous data channels are established. The anonymity is guarantied by randomly chosen pseudonyms owned by a user. Nodes of the network are publicly identified and are independent of users＇ pseudonyms. The article described a network model of the process of implementation of the protocol, and its security is analyzed in brief.
