Two new infinite families of APN functions in trivariate form
K Li, N Kaleyski - IEEE Transactions on Information Theory, 2023 - ieeexplore.ieee.org
We present two infinite families of APN functions in trivariate form over finite fields of the
form. We show that the functions from both families are permutations when is odd, and are 3 …
