Abstract In this paper, we give differential-linear cryptanalysis of SIMON, which is a family lightweight block ciphers published by the National Security Agency, and SIMECK, proposed Yang et al. Firstly, all input difference output masks with one active bit are traversed to obtain 9-round SIMON32/64 distinguisher 10-round SIMECK32/64 distinguisher. Then, 12-round bias 2 −12.69 13-round −14.03 ...
