摘　　要：无线局域网已成为电子政务网的重要组成部分,但是由于数据无线传输,所以窃听、身份假冒和信息篡改等攻击对无线局域网构成了威胁,无线接入的便利性同时带来了很多安全隐患。文中主要研究在电子政务具体应用时无线局域网的身份认证设计与实现,分析了当前无线局域网存在的安全威胁,在现有无线局域网基本认证的基础上实现了一种分层认证协议模型,该模型主要包括三方面内容:公钥证书链的形成,域内认证,域间认证。最后用OPNET实现了无线局域网仿真,并在此基础上做了简单的系统性能分析。WLAN has been the important part of the network of E-government affair. But, because of wireless data transmission, WLAN has been threatened by some attacks such as wiretapping, counterfeiting identity, sophisticating information and so on. The design and realization of identity authentication in WLAN, considering the material application in E-government. are mainly studied Firstly analyzing the existent menace of security, and then the model of layered authentication protocol has been designed based on the existing essential authentication in WLAN. It included contents of three aspects： the forming of the chain of public key certificate, authentication in domain, authentication between domains. At last, through using the OPNET, The simulation of WLAN and ordinarily analyzed the performance of system are realized.
