An Area Efficient Approach to Design Self-Timed Cryptosystems Combatting DPA Attack
D.-W. LEE · IEICE Transactions on Fundamentals of Electronics Communications and Computer Sciences · 2005
Cryptosystems for smartcard are required to provide protection from Differential Power Analysis (DPA) attack. Self-timed circuit based cryptosystems demonstrate considerable resistance against DPA attack, but they take substantial circuit area. A novel approach offering up to 30% area reduction and maintaining DPA protection level close to DIMS scheme is proposed.
