| 摘 要： | 介绍了采用IEEE．802．1Ib协议的无线局域网相关概念和基本安全机制，从加密和认证2个方面，重点分析了无线局域网的安全缺陷及引起的攻击方式，最后讨论了改进的安全措施和方案。通过分析可以看出目前在市场处于主流地位的IEEE802．1Ib无线局域网存在较多的安全隐患，因此，WPA、802．11i和WAPI等新的安全机制被提出，部分弥补了现有的安全问题，但它们到底能从多大程度上可以保证无线局域网安全还有待进一步的验证。

| Abstract: | The paper introduces the concept and basic security mechanism of WLAN briefly, and especially analyzes the security weaknesses of WLAN and attacks to WLAN with respect to encryption and authentication. Finally, the improved security measures and solutions are discussed. Through an analysis, the hidden risks in WLAN are found, so some new security protocols are presented, such as WPA, 802.11i and WAPI etc., which may partly solve the problems, but still needs to be verified for how much security they may guarantee for WLAN. |
