Finding new (up to CCZ-equivalence) constructions of APN functions is one of the important but difficult topics in the study of cryptographic functions. Up to now, only 6 infinite families of power APN functions and 14 infinite families of APN polynomials are known. Although the CCZ-equivalence between power APN functions has been completely characterized, a similar theoretical analysis between polynomial APN functions and power APN functions is still missing. In this paper we prove that, in dimension not multiple of 3, a recently introduced fa...
