摘　　要：当前网络犯罪越来越严重,破解犯罪嫌疑人计算机中的的密码信息则需要技术支持。文章研究了彩虹表的构造原理、破解密码口令的过程,并结合MIC众核协处理器强大的计算能力,设计实现了密码口令破解彩虹表查找系统,并行化的设计提高了彩虹表的生成速度,归约函数的设计提高了明文查找成功率。At present,cyber crimes are becoming more and more serious.It requires technical support to crack the password information in the suspect's computer.In this paper,the construction principle of rainbow table and the process of password cracking are studied.Combined with the powerful computing power of MIC,a password cracking system based on rainbow table lookup is designed and realized.The design of parallelization improves the generation speed of rainbow table,and the design of reduction function improves the success rate of plaintext search.
