Algorithmic Confusion Analysis of Higher Order DPA against Masking Protected Devices
Presenter: Adam Ding (Northeastern University)
Masking the internal operations with random numbers is a popular countermeasure to protect cryptographic systems against differential power analysis (DPA). Higher order DPA can be used to break the masking protection. We apply the algorithmic confusion analysis (Fei et al. 2012 CHES) on higher order DPA. We derive an analytic success rate formula that explicitly shows the effect of the algorithmic properties, the implementation singal-noise-ratio, and masking. We also formally prove that, in the very noisy scenarios, the centered product combination function is optimal for the higher-order attacks.
Adam Ding is an associate professor in the Mathematics Department of Northeastern University. He received his Ph.D. degree from Cornell University. His research focus on statistical methodology and applications in biostatistics, engineering and finance. He had hold summer visiting faculty positions in the Biostatistics Departments of Harvard University and University of Rochester. Recently, he is building statistical models for evaluating side-channel-attacks against cryptosystems.
