WPA模式下无线局域网的攻击与防御

Attack and Defense of WPA-based WLAN

无线局域网的灵活性与移动性使其获得了飞速发展,如今已广泛的分布在各种网络工作环境中。与此同时,不少黑客将计算机攻击手段从有线攻击转向无线攻击。WPA加密技术作为目前主流的无线网络安全技术,已然成为黑客攻击的主要目标。通过对WPA上常用的几种协议进行分析,简述其运行机制,剖析技术上的漏洞,有针对性的提出相应的防御措施,保障用户信息安全。

Theflexibility and mobility of WLAN make it develop rapidly, and now it is widely distributed in various network working environments.At the same time,many hackers turn the means of computer attack from wired attack to wireless attack.As the mainstream wireless network security technology, WPA encryption technology has become the main target of hacker attacks.Through the analysis of several protocols commonly used in WPA encryption technology, this paper brieflyescribes its operation mechanism, analyzes technical vulnerabilities, and puts forward corresponding defensive measures to protect user information security.
