- In this paper, a software interruption-based method is proposed so as to improve ECC processor’s capability against DPA attack. Firstly, we analyze the principium of DPA-resilient time-randomizing. Secondly, combined with operational characteristics of ECC processor, a time-randomizing circuit is put forward. Finally, a power consumption simulation platform is raised for the purpose of making simulation analysis of the proposed circuit. The result shows that our product is secure against DPA attack and is hard to be excluded by differentiation functions aiming at power consumption track simultaneously, which meets the demand of DPA-resilient ECC processor.
