Abstract:

In this paper, we study the permutation property of pentanomials with the form xrh(xp) over Fp, where p∈{2,3}. More precisely, based on some seventh-degree and eighth-degree irreducible pentanomials over F2, we present eight classes of permutation pentanomials over F2 by determining the solutions of some equations with low degrees. In addition, based on the investigation of algebraic curves associated with fractional polynomials over finite fields, eight classes of permutation pentanomials over F3 are discovered by choosing some seventh-degree irreducible pentanomials over F3. Finally, several classes of permutation pentanomials and heptanomials over F2 and F3 are derived from known permutation polynomials on μ2 and μ3, respectively, where μd is the set of d-th roots of unity. © 2023 Elsevier Inc.
