Power analysis for clock fluctuation LSI

Several measures against power analysis attacks have been proposed. A clock fluctuation LSI, which achieves tamper resistance against electromagnetic analysis attacks, is one of popular measures. The present study proposes an alignment method which can analyze the clock fluctuation LSI. The proposed method corrects a shift of power consumption waveforms in the time axis direction caused by periodic fluctuation of clocks. Evaluation experiments using an actual device prove the validity of the proposed method.
