摘　　要：无线局域网给我们的工作和生活带来了很大的便利,但由于网络协议标准本身存在的安全漏洞以及部分用户保密意识不强,使得无线局域网的安全问题日益突出,由此引发的数据泄密以及网络攻击给社会、企业和个人带来不可挽回的损失.本文主要介绍了无线局域网中广泛使用的WEP和WPA/WPA2加密协议的概念和存在的安全隐患,并通过实例对这些协议的脆弱性进行了研究分析,最后提出了如何加强无线局域网安全的防范措施.WLAN brings great convenience to our work and life, but because of security flaws existing in the stand- ard protocol of networks-self and wake of eonfidentiality consciousness in the partial user, security problem of WLAN have become increasingly prominent, the resulting data leaks and network attacks caused irretrievable losses to society, enterprise and individual. This article mainly introduced the concept of cryptographic protocol and security risks of WEP and WPA/WPA2 that widely used in WLAN, the research and analysis for the vulnerability of these protocols is illustra- ted in the article by examples, finally, how to strengthen the precautionary measure of WLAN security was proposed.
