Driven by the insatiable demand of real-time graphics, especially from the market of computer games, Graphics Processing Unit (GPU) is becoming a major computing horsepower during recent years since the performance of GPU is surpassing that of the contemporary CPU. This paper presents our study on how to efficiently recover the passwords for encrypted RAR […]
Protecting data by passwords in documents such as DOC, PDF or RAR, ZIP archives has been demonstrated to be weak under dictionary attacks. Time for recovering the passwords of such documents mainly depends on two factors: the size of the password search space and the computing power of the underline system. In this paper, we […]
Graphics processing unit GPU supports data parallel computation through single instruction multi-data, and provides powerful logic computation ability. We have testified that RAR password decryption rate is greatly improved utilizing parallel computation ability of GPU.
