基于IEEE802.11无线局域网的安全性研究

随着无线局域网的不断发展，网络安全问题日益突出。这里根据无线局域网信道的特点，首先介绍了无线局域网的安全需求，其次，描述了基于IEEE802．11无线局域网标准的有线等效保密（WEP）协议原理，并对WEP协议存在的安全漏洞及其相应的攻击进行了分析，最后，针对这些安全漏洞和攻击提出了增强无线局域网安全性的改进方案。

Research on security of wireless local area network based on IEEE 802.11

As the increasing development of Wireless Local Area Network(WLAN), the security issues become more and more noticeable. First the security requirement of WLAN is introduced based on the characteristic of WLAN channel, and then the principle of Wired Equivalent Privacy(WEP) protocol of IEEE802.11 WLAN standard is presented, and the existing security weakness of WEP protocol and corresponding attacks are also (analyzed), finally some improved schemes to these weakness and attacks are proposed to enhance the security of IEEE802.11WLAN.
