OR AND NOT 1. apn Webthese relations we have the so-called CCZ- and EA-equivalences, and it is im-portant when several functions are considered, to determine whether they corre-spond to each other by such equivalences. CCZ-equivalence is the most general known equivalence relation preserving the APN property [15].

It is currently very difﬁcult to decide, either theoretically or computationally, whether two functions are CCZ equiva- lent, and if so, whether they are EA-inequivalent.

Web1 de set. de 2024 · EA-equivalence is a particular case of CCZ-equivalence, which is the most general known equivalence relation preserving the differential uniformity. An important aspect of the study and the analysis of APN functions, and vectorial Boolean functions in general, is their classification with respect to these equivalence relations. http://boolean.w.uib.no/files/2024/06/marco.pdf
