In this paper, we consider the statistical decision processes behind a linear and a differential cryptanalysis. By applying techniques and concepts of statistical hypothesis testing, we describe precisely the shape of optimal linear and differential distin ...
In this document, we describe the design of a new family of block ciphers, called FOX. The main goals of this design, besides a very high security level, are a large implementation flexibility on various platforms as well as high performances. The high-lev ...
In this paper, we describe the design of a new family of block ciphers based on a Lai-Massey scheme, named FOX. The main features of this design, besides a very high security level, are a large implementation flexibility on various platforms as well as hig ...
Les attaques informatiques sont aujourd'hui l'un des fléaux de notre civilisation. Chaque semaine amène son lot d'alertes concernant des failles dans la sécurité des systèmes d'information, exploitées par pirates et autres créateurs de virus. Ces attaques ...

Although linear perfect diffusion primitives, i.e. MDS matrices, are widely used in block ciphers, e.g. AES, very little systematic work has been done on how to find ``efficient'' ones. In this paper we attempt to do so by considering software implementati ...
Hypothesis tests have been used in the past as a tool in a cryptanalytic context. In this paper, we propose to use this paradigm and define a precise and sound statistical framework in order to optimally mix information on independent attacked subkey bits ...
Linear cryptanalysis remains the most powerful attack against DES at this time. Given 243 known plaintext-ciphertext pairs, Matsui expected a complexity of less than 243 DES evaluations in 85% of the cases for recovering the key. In this paper, w ...
