A function f : Fpn → Fpn is planar, if f(x+a)-f(x) = b has precisely one solution for all a, b e Fpn, a ≠ 0. In this paper, we discuss possible extensions of the switching idea developed in  to the case of planar functions. We show that some of the known planar functions can be constructed from each other by switching.

### Finite Fields and Their Applications

Article history: We present a study of the factorization of the polynomial X m − 1 in M2(F2)(X) and we determine the period of any reversible polynomial of this polynomial ring by using skew

We describe how any function over a finite field F p n can be represented in terms of the values of its derivatives. In particular, we observe that a function of algebraic degree d can be represented

### New Perfect Nonlinear Functions and Their Semifields

• Mathematics
ArXiv
• 2019
Two new classes of perfect nonlinear functions over \$\mathbb{F}_{p^{2m}}\$ are proposed, where p is an odd prime and the nucleus of the corresponding semifields of these functions are investigated and it is shown that they are CCZ-inequivalent to other classes in general.

In this paper we present a new class of perfect nonlinear %Dembowski-Ostrom polynomials over \$\mathbb{F}_{p^{2k}}\$ for any odd prime \$p\$. In addition, we show that the new perfect nonlinear functions

This paper surveys some of these objects which are related to difference set representations of projective planes related to the interplay between the additive and the multiplicative structure of the finite field.

### (2n,2n,2n,1) ‐Relative Difference Sets and Their Representations

We show that every (2n,2n,2n,1) ‐relative difference set D in Z4n relative to Z2n can be represented by a polynomial f(x)∈F2n[x] , where f(x+a)+f(x)+xa is a permutation for each nonzero a. We call

In this article I survey some recent results on planar functions, almost planar functions and modified planar functions from the perspective of difference sets.

### Constructing commutative semifields of square order

The projection construction has been used to construct semifields of odd characteristic using a field and a twisted semifield, so this also constructs new planar functions.

### Further results on differentially 4-uniform permutations over F22m

• Mathematics
ArXiv
• 2015
Several new constructions of differentially 4-uniform permutations over F22m are presented by modifying the values of the inverse function on some subsets of F 22m to provide more choices for the design of crytographic substitution boxes.

It is shown that Alltop type functions cannot exist in fields of characteristic 3 and that for a known class of planar functions, x3 is the only All top type function.
