FPGA ASIC Implementation of Differential Power Analysis Attack on AES

摘要

Advanced Encryption Standard (AES) is a new block cipher standard adopted by U.S. government. Differential Power Analysis (DPA) attack based on correlation coefficient is an effective method to attack the cryptographic device and extract the secret key. Recently, more and more people have become interested in this researching area. In this paper, we built an experiment environment of AES encryption and Correlation DPA attack. We carried out the attack on both FPGA and ASIC board. According to the experiment result, we analyzed the effectiveness and correctness of attack on the two boards. Furthermore, we compared the power data consumed by FPGA and ASIC, and described it in details. Our approach is also the first step to link the effect of attack to the detailed power consumption measurements.
