Impossible Differential Cryptanalysis of Reduced Round SIMON

Zhan Chen, Ning Wang, and Xiaoyun Wang

Abstract

Impossible differential is a useful method for cryptanalysis. SIMON is a light weight block cipher that has attracted lots of attention ever since its publication in 2013. In this paper we propose impossible differential attack on five versions of SIMON, using bit conditions to minimize key bits guessed. We calculate keybits and give the exact attack results.
