A Novel DPA-Resistance Configurable Logic
GU Xiao-chen · Dianzi xuebao · 2011
The efficiency of Differential Power Analysis(DPA) depends on the correlation between power consumption and data value,as well as the attacker′s understanding of circuit details.To counteract DPA attack,this paper presents a novel logic,Dual-Rail Configurable Logic(DRCL),which combines the characteristics of dynamic differential logic and configurable logic.The DRCL has constant power consumption which is independent of the data value.At the same time,the uniform structure of DRCL prevents attackers from revealing circuit details by layout reverse analysis.The experimental results show that the proposed logic DRCL has better power constant than the typical DPA resistant logic WDDL.
