Abstract

In this paper we show an attack on full-round SPECTR H64 and CIKS-1 using related key differential characteristic, which are based on data-dependent rotation with simple key schedule. To find partial 35-bit subkeys of SPECTR-H64 it needs about 2²³ data and 2¹⁶ encryptions with an expected success probability 95.8%. As for CIKS-1, 2⁴ data and 2³³ encryptions are requried to find the final round key of it with an expected success probability 80%.
