Apparatus and method for selecting waveform for side-channel analysis

Abstract

An apparatus and method for selecting a waveform for side-channel analysis are provided. The apparatus for selecting a waveform for side-channel analysis includes a matrix generation unit, a waveform transform unit, and a waveform selection unit. The matrix generation unit generates covariance matrices based on waveforms collected by a waveform collection apparatus. The waveform transform unit determines a 1st principal component using the generated covariance matrices, and to transform the waveforms using the determined 1st principal component. The waveform selection unit selects a waveform for the side-channel analysis from the transformed waveforms.
