To protect security devices such as smart cards against power attacks, we propose a dynamic and differential CMOS logic style. The logic operates with a power consumption independent of both the logic values and the sequence of the data. Consequently, it will not reveal the sensitive data in a device. We have built a set of logic gates and flip-flops needed for cryptographic functions and compared those to Static Complementary CMOS implementations.
