无线局域网的安全机制及安全性分析

Security Mechanism and Analysis of Wireless Local Area Network

简要描述了IEEEStd 80 2 .11- 1999定义的无线局域网的认证、有线网等效加密方案及其使用的RC4算法的加密过程 ,从理论上证明了初始化向量使用和完整性校验方面存在的问题 ,并给出了可能的破解方法 。

The authentication and wired equivalent privacy (WEP) of WLAN are briefly introduced. RC4 encryption algorithm is adopted by WEP, but the usage of initial rector(IV) and information integration check in WEP have theoretically proved to be somewhat unsecure. IEEE 802.11 group presented some improvement schemes to increase the security performance of WLAN.
