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.
