摘要: 为了解决差分能量攻击(DPA)中的样本选取问题,提出了一套样本选取方法。方法从所使用的实验平台出发,通过理论分析提出样本选取方式和数量,然后进行实验验证。以AES算法为例,分别进行了仿真实验和实测实验,验证了所提出的选取方法的准确性。结果表明,仿真攻击的明文样本应该按顺序取,数量为一个全排列,而实测攻击应该直接采用大量随机数,两者对明文样本的要求存在较大差别。

Abstract: To resolve the problem with selecting the samples in the Differential Power Attack (DPA), this paper proposed a set of samples selection method. Based on the given experimental platform, the mode and amount of samples selection were proposed through theoretical analysis, and then were validated by experiments. For Advanced Encryption Standard (AES), this paper put forward the samples selection methods for simulation test and practical experimentation, and proved that the proposed method was right. The results show that the simulation sample plaintext attack should be taken in sequence, with the quantity of a full array. And the attack should be measured directly using a large number of random numbers. There is a big difference in the explicit requirements of the sample.

Key words: Differential Power Attack (DPA), samples select, power trace, Advanced Encryption Standard (AES)
