无线局域网安全问题及解决方案

随着无线局域网（WLAN）的普及,其安全问题越来越受到人们的关注。现有的无线局域网基础设施都支持IEEE802.11或802.11b标准,但这些标准下所定义的加密和认证协议WEP（Wired Equivalent Privacy）协议存在着很多的安全漏洞。首先分析了WEP协议面临的各种安全机制和存在风险。提出了两种弥补漏洞提高WLAN安全性的方案：一种是临时的改进方案,另一种是为了架设新的WLAN基础设施而提出的高级安全方案。最后,提出了实际无线组网安全的几点主观建议。

WLAN Security Issues and Solutions

As the WLAN grows in popularity,more and more people concerned with the security issues.The existing WLAN infrastructure support IEEE802.11 or 802.11b,but defined under the standards of encryption and authentication protocols WEP(Wired Equivalent Privacy)have many security vulnerabilities.This paper analyzes the WEP security protocol and risks first,and then proposes two plug the loopholes to improve WLAN security solutions: A temporary improvement program to set up a new WLAN infrastructure advanced securi...
