Abstract: Recently Matsui announced an attack on the DES algorithm. The attack relies on the approximation of S-boxes by linear functions. To determine the best linear approximation, Matsui defines linear approximation tables (LAT) for S-boxes. In this paper we examine the relation between Matsui's linear approximation tables and the nonlinearities of corresponding S-boxes. 1 Introduction The recent cryptographic attack introduced by Matsui [2] relies on the approximation of S-boxes by linear functions. ...
