Autocorrelations of vectorial Boolean functions

Anne Canteaut and Lukas Kölsch and Chao Li and Chunlei Li and Kangquan Li and Longjiang Qu and Friedrich Wiemer

Abstract: Recently, Bar-On et al. introduced at Eurocrypt’19 a new tool, called the differential-linear connectivity table (DLCT), which allows for taking into account the dependency between the two subciphers E_0 and E_1 involved in differential-linear attacks.

This paper presents a theoretical characterization of the DLCT, which corresponds to an autocorrelation table (ACT) of a vectorial Boolean function. We further provide some new theoretical results on ACTs of vectorial Boolean functions.
