| Abstract(in English) | Piccolo is a 64-bit block cipher proposed by Shibutani et.al in 2011. It has been reported that 8-/10-round Piccolo with 80-/128-bit secret key is attackable by higher order differential attack using 6-round 32-nd order differential characteristic. This paper shows a new higher order differential property of Piccolo. We found a new 7-round 48-th order differential characteristic, and estimates the costs of attack exploiting the characteristic. |
