CCZ-equivalence and Boolean functions
We study further CCZ-equivalence of (n,m)-functions. We prove that for Boolean functions (that is, for m = 1), CCZ-equivalence coincides with EA-equivalence. On the contrary, we show that for (n,m)functions, CCZ-equivalence is strictly more general than EAequivalence when n ≥ 5 and m is greater or equal to the smallest positive divisor of n different from 1. Our result on Boolean functions allo...
متن کاملOn Isotopisms of Commutative presemifields and CCZ-Equivalence of Functions
A function F from Fpn to itself is planar if for any a ∈F ∗ pn the function F (x+ a)−F (x) is a permutation. CCZ-equivalence is the most general known equivalence relation of functions preserving planar property. This paper considers two possible extensions of CCZ-equivalence for functions over fields of odd characteristics, one proposed by Coulter and Henderson and the other by Budaghyan and C...
متن کاملAffine equivalence in the AES round function
In this paper, we show that all the coordinate functions of the advanced encryption standard (AES) round function are equivalent under an affine transformation of the input.We also show that such affine relations will always exist if the AES S-box is replaced by any bijective monomial over GF(28). © 2005 Elsevier B.V.

متن کاملCCZ and EA equivalence between mappings over finite Abelian groups
CCZand EA-equivalence, which are originally defined for vectorial Boolean functions, are extended to mappings between finite abelian groups G and H. We obtain an extension theorem for CCZequivalent but not EA-equivalent mappings. Recent results in [1] are improved and generalized.
متن کاملEA and CCZ Equivalence of Functions over GF(2n)
EA-equivalence classes and the more general CCZ-equivalence classes of functions over GF (2) each preserve APN and AB properties desirable for S-box functions. We show that they can be related to subsets c[T ] and g[T ] of equivalence classes [T ] of transversals, respectively, thus clarifying their relationship and providing a new approach to their study. We derive a formula which characterise...
