Study on DPA countermeasure method using self-timed circuit techniques
비동기회로 설계기술을 이용한 DPA(차분전력분석공격) 방어방법에 관한 연구
Abstract
Differential Power Analysis(DPA) is powerful attack method for smart card. Self-timed circuit has several advantages resisting to DPA. In that reason, DPA countermeasure using self-timed circuit is thought as one of good solution for DPA prevention. In this paper, we examine what self-timed features are good against DPA, and how much we can get benefit from it. Also we test several self-timed circuit implementation style in order to compare DPA resistance factor. Simulation results show that self-timed circuit is more resistant to DPA than conventional synchronous circuit, and can be used for designing cryptographic hardware for smart-card.
