Banik等人在2015年提出的Midori64是一种spn型分组密码，密钥为128位。利用加密函数布尔多项式的高阶微分特性可以进行密码分析。本文给出了Midori64分组密码的各种奇特的三阶微分特征，并对这些特征进行了理论分析。
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.
