一种具有可控匿名性的无线认证协议

Controllable Anonymous Wireless Authentication Protocol

针对无线匿名认证协议中因家乡域身份信息暴露而导致协议匿名性降低及匿名服务滥用的问题,提出一种基于无线网络环境下的可控匿名认证协议。通过使用历史访问域转发认证信息的方法实现家乡域的匿名,通过检查认证标记拒绝非法用户的认证请求,达到对协议的可控性要求。描述协议的实现过程,分析协议的安全性和匿名性。分析结果表明,该协议能提高家乡域的匿名性,可有效控制匿名的滥用。

An anonymous authentication protocol is proposed to improve the anonymity and to control anonymity abusing for wireless communications. The protocol implemented the anonymity of Home Location Register（HL, R） using Visitor Location Register（VLR） which has been employed to forward the authentication message by Mobile Station（MS）. Through checking the authentication token, this protocol can control anonymity abusing. The probability statistics is adopted to analyze the security and anonymity of this protocol. The analysis results show that this protocol not only improves the anonymity of HLR but also defends anonymity abusing effectively.
