Title:
Another class of quadratic APN binomials over \F_{2^n}: the case n divisible by 4

Authors: Lilya Budaghyan, Claude Carlet, Gregor Leander

Abstract:

We exhibit an infinite class of almost perfect nonlinear quadratic binomials from \mathbb{F}_{2^{n}} to \mathbb{F}_{2^{n}} with n=4k and k odd. We prove that these functions are CCZ-inequivalent to known APN power functions when k\ne 1. In particular it means that for n=12,20,28, they are CCZ-inequivalent to any power function.
