| Abstract(in English) | In this paper, we focuse on the saturation attack on block cipher HyRAL that was proposed by Hirata in 2010. It has been shown that 12-round with 256-bit secret key is attackable by higher order differential attack using 7-round synchronous higher order differential characteristics. Based on this characteristics, this paper shows a new 9-round saturation characteristics of HyRAL using 64-th order differential, and estimates the costs of the attack using them. For the case of a 256-bit secret key, it is possible to apply the saturation attack to 13-round HyRAL. |
