摘要

The Simeck family of lightweight block ciphers was proposed in CHES 2015 which combines the good design components from NSA designed ciphers SIMON and SPECK. Dynamic key-guebing techniques were proposed by Wang et al. to greatly reduce the key space guebed in differential cryptanalysis and work well on SIMON. In this paper, we implement the dynamic key-guebing techniques in a program to automatically give out the data in dynamic key-guebing procedure and thus simplify the security evaluation of SIMON and Simeck like block ciphers regarding differential attacks. We use the differentials from Kölbl et al.'s work and also a differential with lower Hamming weight we find using Mixed Integer Linear Programming method to attack Simeck. We improve the previous best results on all versions of Simeck by 2 rounds.
