Extracted version of the ASCADv2 dataset provided by the "Agence nationale de la sécurité des systèmes d'information" (ANSSI). https://www.data.gouv.fr/fr/datasets/ascadv2/ Training traces : 250k, Leakages from the masks, and mixed bytes from subbytes inputs, subbytes output and permutations (shape :(250000,4749)) Test traces : 50k, Leakages from the masks, and mixed bytes from subbytes inputs, subbytes output and permutations (50000,4749) Attack traces, 50k Leakages from the masks, and all bytes from subbytes inputs, outputs and permutations (50000, 28734) The labels corresponding to the extracted leakages are provided in the dataset. The key is artificially fixed (t = p1 + k_random => t = p2 + k_fixed), since all keys are random in the original dataset. Fixed value : 0x00112233445566778899AABBCCDDEEFF.
