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)
