基于IEEE802.11b标准的无线局域网安全研究

Research into Security of WLAN Based on IEEE802.11b

分析了基于国际电器和电子工程师委员会(InstituteofElectricalandElectronicsEngineer,IEEE)802.11b标准的无线局域网的加密算法(WiredEquivalentProtorcol,WEP)存在的安全漏洞,针对各自的缺陷详细地提出了改进措施,并对802.11x/EAP(扩展认证协议),无线局域网鉴别和保密基础结构(WlanAuthenticationandPrivacyIntranstructure,WAPI)等安全协议从认证、加密、完整性校验等方面进行了较深入地研究,指出了单一技术不能解决安全问题,应结合多种措施与技术来建立多层次的安全体系结构,最后提出了一种企业局域网的安全解决方案。

This paper analyses the WEP security mechanism of WLAN based on IEEE802. 11b, discusses the security solutions and technologies of WLAN in detail, deeply studies the authentication, key exchange, confidentiality mechanism of the wireless security protocols, such as 802.11x/ EAP and WAPI, and finally proposes an enterprise application of WLAN.
