摘要
为了达到与有线网络相同的安全性,IEEE802.11协议在MAC层引入安全机制,提供鉴别和保密服务,其核心是协议定义的WEP(wiredequivalentprivacy)算法。本文系统地介绍IEEE802.11的安全机制的构成以及认证、加密、和WEP算法,对其安全性能进行分析,指出存在的安全隐患,并对当前关于增强无线局域网安全性的有关方案进行探讨。
To make the wireless LAN as secure as wired LAN, IEEE802.11 introduces Security Mechanism in the MAC layer and provides authentication and privacy services. The critical component of the security mechanism is Wired Equivalent Privacy algorithm defined by the protocol. The paper describes the current IEEE802.11 security mechanism systematically, describes the authentication, privacy and WEP algorithm, analyses its performance of the mechanism and discussed its flaws. Then introduces the current work on WLAN＇s security enhancement briefly.
