Abstract

In this paper, two new classes of perfect nonlinear functions over Fp2m\mathbb{F}_{p^{2m}} are proposed, where pp is an odd prime. Furthermore, we investigate the nucleus of the corresponding semifields of these functions and show that the semifields are not isotopic to all the known semifields. Particularly, the new perfect nonlinear functions are CCZ-inequivalent to other classes in general.
