Abstract

Password recovery of WPA/WPA2-PSK is an important problem in computer forensics. It is difficult to deal with this problem by traditional methods such as brute force, rainbow table, dictionary, and so on. We give a new method based on parallel random search to solve this problem. This method integrates the advantages that random search can improve the hit rate and the parallel search can improve the operating efficiency. The principle and implementation of this method is also given based on GPU. Finally the test results show that this method can improve the speed of the password search for WPA2-PSK.
