A note on verifying the APN property
Pascale Charpin and Gohar M. Kyureghyan
Abstract: We show that for an arbitrary mapping $F$ on $F_2^n$ to verify that it is APN, it is enough to consider the difference mappings of $F$
defined by elements from an hyperplane.
Category / Keywords: secret-key cryptography / Boolean function, APN functions, hyperplane, cryptographic criteria, differential uniformity.
