In order to alleviate the burden of short keys, encrypting a multiple times has been proposed. In the multiple encryption mode, there may be encryptions under the same or different keys. There have been several attacks against this encryption mode. When tr ...
Ce logiciel, appelé Simsen, est bâti sur une structure modulaire, chaque module renferme la modélisation d'un composant (machines électriques, convertisseurs, transformateurs, lignes, éléments mécaniques, équipements de contrôle-commande et de réglages ana ...
The main goal of this diploma work is the implementation of Matsui's linear cryptanalysis of DES and a statistical and theoretical analysis of its complexity and success probability. In order to achieve this goal, we implement first a very fast DES routine ...
Le présent manuel de conception des chaussées s'adresse aux ingénieurs et aux techniciens oeuvrant dans le domaine de la construction et de l'entretien des chaussées en Suisse. L'ouvrage fournit les outils et conseils nécessaires au dimensionnement d'une c ...
Les principes de la procédure développée pour la définition et l’analyse des caractéristiques du moteur sont décrits dans la première partie du rapport, puis les possibilités d’utilisation de cette procédure sont décrites dans la deuxième partie. Les annex ...
The block cipher MMB was designed by Daemen, Govaerts and Vandewalle, in 1993, as an alternative to the IDEA block cipher. We exploit and describe unusual properties of the modular multiplication in ZZ232 −1 , which lead to a differential attack on the full ...
In this paper we present a new statistical cryptanalytic technique that we call improbable differential cryptanalysis which uses a differential that is less probable when the correct key is used. We provide data complexity estimates for this kind of attack ...
3-D monolithic integration (3DMI), also termed as sequential integration, is a potential technology for future gigascale circuits. Since the device layers are processed in sequential order, the size of the vertical contacts is similar to traditional contac ...

Triple encryption was proposed to increase the security of single encryption when the key is too short. In the past, there have been several attacks in this encryption mode. When triple encryption is based on two keys, Merkle and Hellman proposed a subtle ...
