摘要
介绍了Wi-Fi联盟的WPS标准并给出了对应的攻击方法——暴力破解攻击,使用CPN对WPS协议及改进协议进行形式化分析并证明AP限制重新发起连接认证的次数为3次时,原协议可完全被攻破而给出的改进协议成功概率仅约为3/108。
In this paper, an overview of Wi-Fi Protected Setup （WPS） is supplied. A brute force attack is pointed out. Using Colored Petri Nets（CPN）, the WPS protocol and the improvement are modeled and it is proven that the security flaws exist and the brute force attack is available. Moreover, under setting retry times of connection authentication to be three times, the original protocol can be completely breached and the success breach probability of the improved protocol is only about 3/108.
