On the Non-linearity of Power Functions
Résumé
We study the Boolean functions arising from power functions by means of Stickelberger's con- gruences on Gauss sum. We obtain a new criterion for high non-linearity of such boolean functions in terms of permutation polynomials. Finally, a new characteristic property of Gold exponents is given.
