SIGNAL COMPRESSION APPARATUS AND METHOD FOR POWER ANALYSIS ATTACK CAPABLE OF IMPROVING THE PERFORMANCE OF POWER ANALYSIS BY CALCULATING A WEIGHT VECTOR

摘要

PURPOSE: A signal compression apparatus and method for power analysis attack are provided to calculate a weight vector by using principal component analysis considering a property of a power waveform signal.;CONSTITUTION: A signal about one or more predetermined clocks is extracted from power waveform signals(110). The predetermined clock is corresponded to one clock selected from a plurality of clocks. Each weighted value for elements of an extracted signal is determined based on the characteristic of the power waveform signal. A weight vector is calculated using the weighted value. An optimal weight vector is calculated by considering the characteristic of the power waveform signal(120). A compressed signal is generated by multiplying the weight vector(130).;COPYRIGHT KIPO 2012
