Impossible Differential Attack on Reduced Round SPARX-64/128

Abstract

SPARX-64/128 is an ARX-based block cipher with 64-bit block size and 128-bit key. It was published in Asiacrypt 2016 as one of the instantiations of a family of ARX-based block ciphers with provable security against single-characteristic differential and linear cryptanalysis. In this work, we present 12 and 13-round impossible distinguishers on SPARX-64/128… (More)
