Security analysis of WPS in WLAN
Liu Yongle · Computer Engineering and Applications Journal · 2013
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.
