This paper describes a design method to secure encryption algorithms against Differential Power Analysis at the logic level. The method employs logic gates with a power consumption, which is independent of the data signals, and therefore the technique removes the foundation for DPA. In a design experiment, a fundamental component of the DES algorithm has been implemented. Detailed transistor level simulations show a perfect security whenever the layout parasitics are not taken into account.
