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 $F_{r} (x) = x^{r} (1 + I ¨ (x))$ over $F_{p^{n}}$ have shown that these functions can exhibit very low boomerang uniformity. In this paper,…

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…

On Differential and Boomerang Properties of a Class of Binomials over Finite Fields of Odd Characteristic

Namhun Koo, Soonhak Kwon

In this paper, we investigate the differential and boomerang properties of a class of binomial $F_{r, u} (x) = x^{r} (1 + u I ¨ (x))$ over the finite field $F_{p^{n}}$ , where $r = \…
