Description
Even if recent advances in public key cryptography tend to focus on algorithms able to survive the post quantum era, at present, there is a urgent need to propose fast, low power and securely implemented cryptography to address the immediate security challenges of the IoT. In this talk, we present a new set of Binary Edwards Curves which have been defined to achieve the highest security levels (up to 284-bit security level) and whose parameters have been defined to fit IoT devices embedding 32-bit general purpose processors. We optimized the choice of the point generator with the w-coordinate to save a multiplication in the addition and doubling formulae. We manage to compute one step of the Montgomery Ladder in 4 multiplications and 4 squares. On top of the performance benefits, cryptography over such curves have some intrinsic security properties against physical attacks.

Les jeux vidéo de l’écran au réel : enjeux juridiques et (géo)politiques au prisme de la cybersécurité
Speaker : Léandre Lebon, Sandrine Turgis - Univ Rennes, IODE
Protection des droits d’auteur, lutte contre les techniques de triche, interactions avec la guerre et les conflits hybrides, enjeux de démocratie ... Sous l’angle de la cybersécurité les enjeux juridiques et (géo)politiques des jeux video sont nombreux. Cette présentation du groupe de travail sur les jeux video (GTJV) permettra d’alimenter la réflexion sur l’articulation entre jeux video et[…]-

The Quest for my Perfect MATE. Investigate MATE: Man-at-the-End attacker (followed by a hands-on application).
Speaker : Mohamed Sabt, Etienne Nedjaï - Univ Rennes, IRISA
Shannon sought security against an attacker with unlimited computational powers: if an information source conveys some information, then Shannon’s attacker will surely extract that information. Diffie and Hellman refined Shannon’s attacker model by taking into account the fact that the real attackers are computationally limited. This idea became one of the greatest new paradigms in computer[…]
