基于WEP协议的无线局域网安全性分析与测试

A Testing and Analysis of the Security of WLAN Based on WEP

随着WLAN技术的发展成熟,其安全性正日益受到人们的重视.由于WLAN使用的无线媒体具有开放信道的特点,因此其对安全性的要求比在有线环境下更高也更严格.作为目前使用最广泛的无线局域网标准,IEEE 802.11b使用WEP协议来保证无线网络环境下的数据安全.文中简要介绍了WEP协议的实现原理,着重分析了WEP存在的安全隐患,并利用Airsnort软件对其进行了安全性测试.

Along with the development of WLAN,people are more and more aware of its security. Because data is transferred in open signal path, the security level of WLAN is higher than LAN. As the most popular standard of WLAN, IEEE802. llb uses WEP to protect the data transmission. This article makes a brief introduction to the principle of WEP,puts emphasis on the hidden dangerous attached to it,and ：then,tests the security of WEP with Airsnort.
