A generalization of the map $χ$

Xiutao Feng, Qiang Wang, Jingyi Yu +1

The mapping $χ_{n} : F_{2}^{n} \to F_{2}^{n}$ defined by $y = χ_{n} (x)$ with $y_{i} = x_{i} + x_{i + 1} x_{i + 2} + x_{i + 2}$ , where the indices are computed modulo $n$ , has been widely s…

On the Derivative Imbalance and Ambiguity of Functions

Shihui Fu, Xiutao Feng, Qiang Wang +1

In 2007, Carlet and Ding introduced two parameters, denoted by $N b_{F}$ and $N B_{F}$ , quantifying respectively the balancedness of general functions $F$ between finite Abelian groups a…

Further Results of the Cryptographic Properties on the Butterfly Structures

Shihui Fu, Xiutao Feng

Recently, a new structure called butterfly introduced by Perrin et at. is attractive for that it has very good cryptographic properties: the differential uniformity is at most equa…
