Comparative Analysis of Two Kinds of Power Attacks on DES Cryptographic Chip
Bin Yang · Journal of Chengdu University of Information Technology · 2012
Introduced the Differetial Power Analysis(DPA) and Correlation Power Analysis(CPA) methods and their analysis process.According to the DES cryptographic algorithm,realized the DPA attack and CPA attack in the independent researched and developed power analysis platform.The experiment results analysis shows that the two methods have their own characteristics.DPA is insensitive to device noise with general analysis ability.CPA is a greater threat to the encryption device-with less power consumption but sensitive to device noise.By integrating the two methods in the power anlaysis platform,can greatly improve the attack efficiency and suitability.
