Differential attacks on reduced SIMON versions with dynamic key-guessing techniques

Abstract

SIMON is a family of lightweight block ciphers which are designed by the U.S National Security Agency in 2013. It has totally 10 versions corresponding to different block size 2n and key length lk, named as SIMON2n/lk. In this paper, we present a new differential attack by considering the sufficient bit conditions of the previous differential paths. Based… (More)
