A note on the differential spectrum of a class of locally APN functions

Haode Yan, Ketong Ren

Let $\gf_{p^n}$ denote the finite field containing $p^{n}$ elements, where $n$ is a positive integer and $p$ is a prime. The function $f_{u} (x) = x^{\frac{p ^{n} + 3}{2}} + u x^{2}$ over $\gf_{p^n…

A note on the differential spectrum of the Ness-Helleseth function

Ketong Ren, Maosheng Xiong, Haode Yan

Let $n ⩾ 3$ be an odd integer and $u$ an element in the finite field $\gf_{3^n}$. The Ness-Helleseth function is the binomial $f_{u} (x) = u x^{d_{1}} + x^{d_{2}}$ over $\gf_{3^n}$, wher…
