Özet

In this article we are interested in the class of permutation polynomials of the form: [Formula Presented] where d and r are positive integers and d divides q − 1. We give necessary conditions and sufficient for this family of polynomials to be permutations in a finite field Fq of characteristics 7, based on the Lidl-Wan criterion. Then we will give an application in cryptography for this family of polynomials on Fq.
