On APN Functions with Boomerang Uniformity One over $F_{3^{n}}$ : Differential and Boomerang Spectra and CCZ-Inequivalence

Namhun Koo, Soonhak Kwon, Minwoo Ko +1

Let $q = 3^{n}$ , where $n > 1$ is odd, and let $g:\Fq\to\Fq$ be a perfect nonlinear (PN) function represented by a Dembowski--Ostrom (DO) polynomial. Put $τ = g (1)$ , let $ε$ be the indicat…

On APN Exponents and the Differential and Boomerang Properties of Binomials in Characteristic 3

Namhun Koo, Soonhak Kwon, Minwoo Ko +1

Recent studies on binomials of the form $F_{r} (x) = x^{r} (1 + χ (x))$ over $F_{p^{n}}$ have shown that these functions can exhibit very low boomerang uniformity. In this paper, w…

Locally-APN Binomials with Low Boomerang Uniformity in Odd Characteristic

Namhun Koo, Soonhak Kwon, Minwoo Ko +1

Recently, several studies have shown that when $q \equiv 3 (mod 4)$ , for certain choices of $r$ , the function $F_{r} (x) = x^{r} + x^{r + \frac{q - 1}{2}}$ defined over $\Fq$ is locally-APN and h…
