Weights on affine subspaces and some other cryptographic characteristics of Boolean functions of 5 variables

Evgeny K. Alekseev and Lyudmila A. Kushchinskaya

Abstract

Recently one new key recovery method for a filter generator was proposed. It is based on so-called planar approximations of such a generator. This paper contains the numerical part of the research of the Boolean functions properties which allow to protect the generator against this method. The main theoretical part of this research is presented at the CTCrypt 2019 conference.
