Cracking of WPA & WPA2 Using GPUs and Rule-based Method

摘要

Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols developed by the Wi-Fi Alliance to secure wireless computer networks. The prevailing usage of GPUs improves the brute force attacks and cryptanalysis on access points of the wireless networks. It is time-consuming for the cryptanalysis with the huge total combinations of 95(63) max. Now, it is the turning point that the leap progress of GPUs makes the Wi-Fi cryptanalysis much more efficient than before. In this research, we proposed a rule-based password cracking scheme without dictionary files which improves the efficiency of cracking WPA/WPA2 protected access points. The experiment was performed on the real environment and the results demonstrate that the proposed scheme. The proposed scheme improves the efficiency from 2088000 PMKs/min to 16200000 PMKs/min.
