HyRAL is a 128-bit block cipher proposed by Hirata in 2010. It has been reported that 14-round HyRAL with 256-bit secret key is attackable by saturation attack using 10-round 64-th order differential characteristic. This paper shows a new higher order differential property of HyRAL. With control transform and observation transform, we found a 11-round saturation characteristic using 104-th order differential. By a close analysis of byte-values, the reason why such characteristic holds is clarified. If we use it, for the case of a 256-bit secret key, it is possible to apply the higher order differential attack to 16-round HyRAL using the partial sum technique proposed by Ferguson et al. |
