An almost perfect nonlinear (APN) function (necessarily a polynomial function) on a finite field F is called exceptional APN, if it is also APN on infinitely many extensions of F. In this article we consider the most studied case of F = F 2 n. A conjecture of Janwa-Wilson and McGuire-Janwa-Wilson (1993/1996), settled in 2011, was that the only exceptional(More)
Almost Perfect Nonlinear (APN) functions are very useful in cryptography , when they are used as S-Boxes, because of their good resistance to differential cryptanalysis. An APN function f : F 2 n → F 2 n is called exceptional APN if it is APN on infinitely many extensions of F 2 n. Aubry, McGuire and Rodier conjectured that the only exceptional APN(More)
