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.
