A New Protect Cryptographic Circuit Approach Using Dynamic Current Model Logic Circuit

Power analysis attacks have attracted significant attention within the cryptographic community. Power analysis attack methods for encryption circuits are being discussed. Unique masking method (UMM) are being discussed, point out it is vulnerable to higher-order differential power analysis. Propose a new method which uses dynamic current model logic (DCML) circuit. The circuit can defeat higher-order differential power analysis (DPA) with increased reasonable area and power consumption. Our experiments show its efficiency.
