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
