APPARATUS AND METHOD FOR GENERATING POWER SIMULATION WAVE IN CRYPTO ALGORITHM HARDWARE

摘要

PURPOSE: A device for generating a power simulation waveform in encryption algorithm hardware and a method thereof are provided to easily implement sub channel analysis or safety evaluation. CONSTITUTION: An input part(100) receives an input text with a plurality of bits corresponding to the power state of encryption hardware. A separation part(200) separates the input text into a plurality of groups including at least one bit or into a plurality of groups according to time. A waveform application part(300) searches for waveforms, corresponding to each group separated from the separation part, in a waveform storage part(350) and applies the searched waveform to corresponding groups. An integration part(400) integrates all the waveforms for each group and finally generates a power simulation waveform in encryption algorithm hardware.
