A few more quadratic APN functions
We present an infinite family of quadrinomial APN functions on GF(2 n ) where n is divisible by 3 but not 9. The family contains inequivalent functions, obtained by setting some coefficients equal to 0. We also discuss the inequivalence proof (by computation) which shows that these functions are new.
