Abstract

In this paper, we present a function in \(\mathbb{F}_2[X]\) and prove that several of its properties closely resemble those of Euler’s φ function. Additionally, we conjecture another property for this function that can be used as a simple primality test in \(\mathbb{F}_2[X]\), and we provide numerical evidence to support this conjecture. Finally, we further apply the previous results to design a simple primality test for trinomials.
