基于Open CL的MD5破解算法

摘要

This paper uses Open Computing Language(OpenCL) to realize the decrypting algorithm on heterogeneous platforms with Graphic Processing Unit(GPU).By using multi rounds attacking, graphics pipeline accelerates accessing and multi key attacking, the code runs 18 times faster on a NVIDIA GT200 GPU with Intel Q8230 quad-core CPU(2.3 GHz) than the decryption software, John the ripper, running on the same CPU-only platform.%在基于GPU的异构平台上,采用开放计算语言(OpenCL)实现破解算法,利用分轮生成攻击密码、图形演染管线加速存取以及多密码并行等方法对算法进行优化,在Intel四核CPU Q8230(2.3GHz)和一片NVIDIA GT200组成的平台上进行实验.实验结果表明,在相同CPU平台上该算法能够获得高于破解软件John the ripper 17倍的破解速度.
