摘要/Abstract

摘要： 利用DFA攻击方法的1比特差分差错模型，分析了DES算法的1比特差分差错所处的位置与密文差分之间的关系，并对分析结果进行了实验测试。利用分析结果，可以根据密文差分的特点有效地判断1比特差错所处的位置，进而顺利地进行DFA攻击。

Abstract: With 1-bit differential fault model of DFA attack against DES algorithm，the relationship between 1-bit differential fault position and ciphertexts’difference is analyzed，and the results are proved to be correct by experiments at the same time.According to these results，the position of 1-bit differential fault can be judged by the character of ciphertexts’ difference，DFA attack can be implemented successfully.
