Electromagnetic (EM) side-channel traces of elliptic curve point multiplication during SM2 decryption in OpenSSL The dataset was used for Test Vector Leakage Assessment (TVLA) of SM2 decryption. The results are presented at ACSAC 2018 (https://www.acsac.org/2018/) in "Side-Channel Analysis of SM2: A Late-Stage Featurization Case Study" (DOI: 10.1145/3274694.3274725). The dataset contains Electromagnetic (EM) side-channel traces of elliptic curve point multiplication during SM2 decryption in OpenSSL. Folders Description EM_traces_before_countermeasures : contains EM traces that were taken on unprotected version of SM2 decryption; EM_traces_after_countermeasures : contains EM traces that were taken after all the countermeasures described in the paper were applied; Data Description These are Matlab generated files (.mat). Each file contains a single Matrix where each column represent an EM trace. The data type is double-precision floating-point (8-bytes). File Name Description TRACE_fixed* : contains traces with fixed key and fixed point (cipher text) TRACE_rand_key* : contains traces with random key and fixed point (cipher text) TRACE_rand_point* : contains traces with fixed key and random point (cipher text)
