采用GPU的ZIP密码恢复算法
ZIP password recovery on GPU
摘要
Abstract
Generally, zip password recovery software uses CPUs to crack password, which can only try a few passwords per seconds, and it takes a long time to find out the correct password. This paper proposes a fast zip password recovery algo-rithm on GPU, the AES decryption and HMAC algorithm are optimized for GPU specially. This algorithm takes advan-tage of password verification value to reject many incorrect passwords. The algorithm uses macro to optimize the usage of GPU registers, the computing resources have been fully used. The experimental result shows that GPU can achieve 11.09 times speedup compared with the CPU.关键词
