The Hidden Side of Jean-Jacques Quisquateras a good idea to present him to you from the prism of his son. I will restrict myself to the scientifical part of our relationship, the rest being kept private..My scientifical education started very early. Indeed, when I didn’t want to eat something as a child, he cut the food in the shape of rock

DES Collisions RevisitedS collisions. We use the same distinguished points method, but in contrast to their work, our aim is to find a large number of collisions. A simple theoretical model to predict the number of collisions found with a given computational effort is developed, and experimental results are given to valida

Line Directed Hypergraphsy parameters of dihypergraphs and their line dihypergraphs, like the fact that the arc connectivity of a line dihypergraph is greater than or equal to that of the original dihypergraph. Then we show that the De Bruijn and Kautz dihypergraphs (which are among the best known bus networks) are iterated

Self-similarity Attacks on Block Ciphers and Application to KeeLoqWagner with a complexity of 2. KeeLoq computations [11]. However this attack requires the knowledge of the whole code-book of 2. known plaintexts, which is totally unrealistic. The first attack on KeeLoq with a far more realistic requirement of 2. known plaintexts was proposed by Courtois, Bard and

Increasing Block Sizes Using Feistel Networks: The Example of the AESt lengths while maintaining the ability to select -a priori- arbitrary security levels. We start from the generation of block ciphers that are simple balanced Feistel constructions that exploit the pseudorandomness of functions, namely the AES, as round function. This results in block ciphers with i

Authenticated-Encryption with Padding: A Formal Security Treatmentn practice against certain implementations of important secure network protocols, including IPsec and SSL/TLS. A formal security analysis of CBC mode in the context of padding oracle attacks in the . was previously performed by the authors. In this paper, we consider the ., examining the question of
