SPARX is a family of ARX-based block ciphers proposed at Asiacrypt 2016. This family was designed with the aim of providing provable security against single-characteristic linear and differential cryptanalysis. SPARX-128/128 and SPARX-128/256 are two members of this family which operate on data blocks of length 128 bits and keys of length 128 and 256 bits, respectively. In this work, we show the existence of zerocorrelation distinguishers for SPARX-128/128 and SPARX-128/256 with length longer… CONTINUE READING
