要約(英語): Recently, several illegal attacks against cryptographic circuits were reported. The template attack is one of the most dreadful attacks. To secure the safety of electronic devices in the future, into which cryptographic circuits have been incorporated, template attacks must be thoroughly studied. Therefore, this paper proposes a new template attack. It performs power analysis in frequency domain in order to improve the performance of analysis, while all previous template attacks perform in time domain. Moreover, the proposed template attack introduces an alignment technique and a selection technique of waveforms. The alignment technique, which corrects positions of waveforms, is suitable for template attacks. The selection technique utilizes equalization of the hamming-distance on each state to reduce noises of an analysis. Several experiments using cryptographic LSI prove the validity of the proposed method.
