An Improved DES Anti-DPA Algorithm and Its Automatic Simulation System

Based on the analysis of DES cryptographic algorithms and anti-attack strategy, this paper proposes an advanced DES anti-DPA attack algorithm by further improving the Mask method in the power consumption points and the simplicity of working codes. And then, we focus on establishing the algorithm and the validation model by using SystemC, after completing the circuit design of such a DES cryptographic coprocessor that meets the requirement of NFC applications. In order to reduce the development time and costs, we construct a set of automatic simulation system for SystemC model and the RTL circuit. Results of the simulation of this experiment procedure are given to prove the proposed algorithm and design effective.
