P $℘$ N functions, complete mappings and quasigroup difference sets

Nurdagul Anbar, Tekgul Kalyci, Wilfried Meidl +2

We investigate pairs of permutations $F, G$ of $F_{p^{n}}$ such that $F (x + a) - G (x)$ is a permutation for every $a \in F_{p^{n}}$ . We show that necessarily $G(x) = \wp(F(x…

The $c$ -differential spectrum of $x \mapsto x^{\frac{p ^{n} + 1}{2}}$ in finite fields of odd characteristics

Constanza Riera, Pantelimon Stanica, Haode Yan

In the paper, we concentrate on the map $x \mapsto x^{\frac{p ^{n} + 1}{2}}$ on $F_{p^{n}}$ and using combinatorial and number theory techniques, we compute its detailed $c$ -diffe…

Low c-differentially uniform functions via an extension of Dillon's switching method

Chunlei Li, Constanza Riera, Pantelimon Stanica

In this paper we generalize Dillon's switching method to characterize the exact $c$ -differential uniformity of functions constructed via this method. More precisely, we modify some…
