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…

An Improvement of the Cipolla-Lehmer Type Algorithms

Namhun Koo, Gook Hwa Cho, Byeonghwan +1

Let F_q be a finite field with q elements with prime power q and let r>1 be an integer with $q \equiv 1 (mod r)$ . In this paper, we present a refinement of the Cipolla-Lehmer type…
