Abstract: Brute force attack on block cipher algorithm is an important direction of cryptology. Software of brute force attack on block cipher algorithms is designed based on distributed computing. Brute force attack on block cipher algorithms DES and SMS4 are simulized in the LAN and the function test to the software is carried on. It analyzes the software and results of brute force attack on DES and SMS4. Experimental results show that this software has strong commonability.

Key words: brute force attack, distributed computation, block cipher

摘要： 暴力破解分组密码算法是密码学的重要研究方向。该文基于分布式算法，设计具有高通用性的暴力破解分组密码软件。在局域网内对分组密码算法DES和SMS4的暴力破解进行模拟实现，测试其性能并分析DES和SMS4的暴力破解结果。实验结果表明，该软件通用性较强。
