摘要:

阐述了针对采用S盒的分组密码差分故障分析原理及模型，将差分故障分析简化为求解S盒输入和输出差分问题，阐述了针对采用S盒的分组密码差分故障分析一般过程。针对采用S盒的分组密码差分故障分析的一般特征和Hash函数不町逆特点，提出了引入Hash函数的抗差分故障分析模型，对Hash函数进行了介绍，并阐述了实验中使用的MD5算法。在ARIA-128中引入文中提出的抗差分故障分析模型。通过对比实验，验证了模型抗差分故障分析能力。此外，所提出的抗差分故障分析模型也为加密算法设计者提供了一定的思路

Abstract:

Presents the principle and model of differential fault analysis on block cipher with S-box, simplifies the differential fault analysis process to getting the input and output difference of S-box, and also presents the DFA process to block cipher with S-box. Accord- ing to the ordinary character of differential fault analysis on block cipher and the Hash function without reversibility ,present the anti-DFA model with Hash function, introduce the Hash function and the MD5 algorithm used in experiments. Eventually,introduce the anti-DFA model to ARIA-128. According to contradistinctive experiments, have validated the anti-DFA ability of the model we presented. On the other hand, the anti-DFA model we presented provides ideas to cipher designers
