New Lightweight DES Variants

In this paper we propose a new block cipher, DESL (DES Lightweight), which is based on the classical DES (Data Encryption Standard) design, but unlike DES it uses a single S-box repeated eight times. On this account we adapt well-known DES S-box design criteria, such that they can be applied to the special case of a single S-box. Furthermore, we show that DESL is resistant against certain types...

Related-Key Attacks on Triple-DES and DESX Variants

In this paper, we present related-key slide attacks on 2-key and 3-key triple DES, and related-key differential and slide attacks on two variants of DESX. First, we show that 2-key and 3-key triple-DES are susceptible to related-key slide attacks. The only previously known such attacks are related-key differential attacks on 3-key triple-DES. Second, we present a related-key differential attack...

Des Propagateurs Indépendants Des Solveurs *

Cet article présente une extension des indexicals pour décrire des propagateurs de contraintes globales. Ce nouveau langage produit par compilation des propagateurs pour différents solveurs et est indépendant d’un solveur particulier. De plus, nous montrons que cette description de haut niveau aide à prouver certaines propriétés telles que correction et monotonie. Des résultats expérimentaux mo...
