DEVICE FOR EVALUATING SIDE-CHANNEL ATTACK RESISTANCE, METHOD FOR EVALUATING SIDE-CHANNEL ATTACK RESISTANCE, AND PROGRAM FOR EVALUATING SIDE-CHANNEL ATTACK

摘要

A side channel attack resistance evaluation apparatus includes: a measurement section that measures side channel information leaking from an encryption device to be evaluated; a noise removal section that removes noise from the measured side channel information using a band-pass filter (BPF); a passband determination section that determines the passband of the band-pass filter; and a DSCA (Differential Side-Channel Analysis) evaluation section that evaluates resistance against the differential side channel analysis. The passband determination section preferably has a DFT processing section and a power spectrum analysis section, or has a DFT processing and a DFA processing section.
