This implements the attack described in Carlo Meijer, Roel Verdult, "Ciphertext-only Cryptanalysis on Hardened Mifare Classic Cards" in Proceedings of the 22nd ACM SIGSAC Conference on Computer and Communications Security, 2015 It uses precomputed tables for many bitflip properties (not only two as in the paper) and is therefore quite efficient. To prevent failing it doesn't do differential analysis with several nonce bytes' Sum(a8) properties (each of them may be wrongly guessed) - instead it concentrates on one nonce byte and tries all Sum(a8) property guesses sequentially (ordered by probability). The brute force phase makes use of aczid's bit sliced brute forcer (https://github.com/aczid/crypto1_bs). Includes runtime CPU-detection to leverage modern (and old) SIMD instructions with a single executable.
