In order to improve the resistance to differential power attack capability of the ECC cryptographic processor, this paper presents the method of time randomization based on soft interrupt resistance to DPA attack. First the principle of the time randomization against DPA attack is analyzed; and then combined with the operational characteristics of ECC processor, this paper designs a time randomized circuit based on soft interrupt request; finally, power simulation platform is built and the design result is simulated. Simulation results show that the design can resist the DPA attack, and power characteristics of time randomization part in energy trace are not easy to be culled. The design achieves requirements of against DPA attack for ECC cryptographic processor.
