Efficient Electromagnetic Analysis for Cryptographic Module on the Frequency Domain

Research output: Contribution to journalArticle

Abstract

An efficient analysis method in the frequency domain for the extraction of information under the degradation of signal-to-noise ratio (SNR) is proposed. When the electromagnetic emission from the cryptographic module on the hardware is analyzed, the electromagnetic fields caused by operation on the other modules interfere to the electromagnetic field from the cryptographic module. Therefore, the amount of the measured data required for the extraction of information under the condition of degraded SNR increases and the analysis for this increase in data needs additional computation time. In order to accelerate the analysis under the degradation of SNR, we focus on only the processing of analysis target data. Furthermore, the signal of information and noises is separated with the analysis on the frequency domain. The proposed method is examined through experiments.
