Blind Side Channel Analysis against AEAD with a Belief Propagation Approach

Résumé

This paper present two new attacks on two lightweight authenticated encryption with associated data (AEAD): Sparkle and Elephant. These attacks are blind side channel analysis (BSCA). The leakage is considered as an Hamming weight (HW) with a Gaussian noise. In both attacks, a belief propagation (BP) algorithm is used to link the different leaks. Another objective is to present BSCA as a new tool for evaluating the robustness of a symmetric cryptographic primitive subfunctions.
