近几年由于无线局域网WLAN(Wi-Fi)的发展迅速,已经广泛的普及到企事业单位、学校和普通居民家庭,无线密钥算法由WEP逐步升级到有更高强度的WPA、WPA2加密方式,使得整个无线局域网体系安全有了大的提高,但同时高强度的密钥增加了接入端用户连接所花费的时间与繁琐程度。Wi-Fi联盟就此问题出台一套解决方案——Wi-Fi Protected Setup,简称WPS,但是这个方案在方便用户连接的同时带来了重大的安全漏洞,使得本来安全性较强的WPA密钥(AES算法)可以在普通家用计算机上2-8小时破解,如果对普通计算机进行改装,如果环境良好估计几小时之内破解不是问题。
In recent years, due to the rapid development of wireless LAN WLAN (Wi-Fi), it has been widely popularized to enterprises, institutions, schools and ordinary households. The wireless key algorithm is gradually upgraded from WEP to WPA with higher strength and WPA2 encryption , Making the entire wireless LAN system security has been greatly improved, but at the same time high-strength key to increase the time spent connecting the user-side and tedious degree. Wi-Fi Alliance on the issue of a solution - Wi-Fi Protected Setup, referred to as WPS, but this program is easy to connect users at the same time brought a major security vulnerability, making the originally strong security WPA key AES algorithm) can be 2-8 hours on a common home computer to crack, if the normal computer to be modified, if the environment is good to estimate within a few hours to crack is not a problem.
