On Known APNs
Val\'erie Gillot ad Philippe Langevin

TL;DR
This paper introduces new invariants and a backtracking method to analyze APN functions, providing evidence that the set of 6-bit APN functions is limited to 14 CCZ-classes, supporting a longstanding conjecture.
Contribution
It presents novel invariants and a systematic approach to classify 6-bit APN functions, advancing understanding of their structure and limitations.
Findings
Supports the conjecture that only 14 CCZ-classes exist for 6-bit APN functions
Introduces an APN-extendibility criterion for classification
Develops a backtracking approach to identify numerical facts about APN functions
Abstract
We present new invariants, APN-extendibility criterion and a backtracking approach to identify several numerical facts supporting the conjecture that the set of 6-bit \APN functions is limited to 14 CCZ-classes.
