Abstract: We present some features of block ciphers based on the three operations: addition mod 2n, rotation and XOR (ARX ciphers) and the main cryptanalitic attacks obtained by developing the methods underlying differential cryptanalysis. We focus on the recent tecnique of rotational XOR differential cryptanalysis giving some ideas of this attack and its application to SPECK 32/64.
