The peculiar third-order differential characteristics of Midori64 block cipher(II)

Midori64 proposed by Banik et al. in 2015 is an SPN-type block cipher with 128-bit secret key. The higher-order differential characteristics of the boolean polynomial of encryption function can be exploited for cryptanalysis. In this paper, we show a variety of the peculiar third-order differential characteristics of Midori64 block cipher, and theoretically analyze the characteristics.
