A new almost perfect nonlinear function which is not quadratic

Yves Edel and Alexander Pott

Abstract

We show how to change one coordinate function of an almost perfect nonlinear (APN) function in order to obtain new examples. It turns out that this is a very powerful method to construct new APN functions. In particular, we show that the approach can be used to construct ``non-quadratic'' APN functions. This new example is in remarkable contrast to all recently constructed functions which have all been quadratic.

Note: One sentence in Theorem 11 (erroneously written in German) has been deleted.
