NLAT: the NonLinear Approximation Table of Vectorial Boolean Mappings

Jorge Nakahara Jr

Abstract

This paper studies an extension of the Linear Approximation Table (LAT) of vectorial Boolean mappings (also known as Substitution boxes) used in Linear Cryptanalysis (LC). This extended table is called NonLinear Approximation Table (NLAT).

Note: A small correction to the title: "Approximation" instead of "Distribution"
