中文摘要：

无线网络是目前网络发展的一个方向和趋势。借助对无线局域网802.11协议及其加密体制的安全性进行分析,从理论上得出原有的802.11协议及其加密体制存在的诸多漏洞。在Linux下对802.11协议中的WEP体制进行攻击实验的测试,尤其是注入式攻击实验,从实际上证明原有802.11协议及其加密体制的脆弱性。

英文摘要：

WLAN is the trends and direction of network development. With the help of the 802.11 wireless local area network and encryption security system to analyze, we theoretically reach a conclusion that there are many loopholes existing in the original IEEE 802.11 along with its encryption system. Then doing the attacking experimental test of the WEP system in the IEEE 802.11 under the Linux operating system, especially spoon-feeding attack experiment, which proves the vulnerability of the original IEEE 802.11 as well as its encryption system.
