有限域上的一些新的置换多项式

Some New Permutation Polynomials over Finite Fields

Nouara Zoubir, Kenza Guenda

摘要:

本文构造了一类新的完全置换单项式和几类置换多项式。进一步,通过给出O-多项式的另一个特征,得到了一类$G(x)+ γTr(H(x))$形式的置换多项式,其中G(X)既不是置换多项式,也不是线性化多项式.这是对Charpin和Kyureghyan在[P. Charpin和G. Kyureghyan,$G(x)+ γTr(H(x))$何时置换$\mathbb{F}_{p^n}$?,有限域及其应用15(2009)615- 632]。

英文摘要:

In this paper, we construct a new class of complete permutation monomials and several classes of permutation polynomials. Further, by giving another characterization of o-polynomials, we obtain a class of permutation polynomials of the form $G(x)+ γTr(H(x))$, where G(X) is neither a permutation nor a linearized polynomial. This is an answer to the open problem 1 of Charpin and Kyureghyan in [P. Charpin and G. Kyureghyan, When does $G(x)+ γTr(H(x))$ permute $\mathbb{F}_{p^n}$?, Finite Fields and Their Applications 15 (2009) 615--632].
