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[…] -
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 Design and Implementation of a Virtual Firmware Monitor
Speaker : Charly Castes - EPFL
Low level software is often granted high privilege, yet this need not be the case. Although vendor firmware plays a critical role in the operation and management of the machine, most of its functionality does not require unfettered access to security critical software and data. In this paper we demonstrate that vendor firmware can be safely and efficiently deprivileged, decoupling its[…]-

Should I trust or should I go? A deep dive into the (not so reliable) web PKI trust model
Speaker : Romain Laborde - University of Toulouse
The padlock shown in the URL bar of our favorite web browser indicates that we are connected using a secure HTTPS connection and providing some sense of security. Unfortunately, the reality is slightly more complex. The trust model of the underlying Web PKI is invalid, making TLS a colossus with feet of clay. In this talk, we will dive into the trust model of the web PKI ecosystem to understand[…]-

Hardware-Software Co-Designs for Microarchitectural Security
Speaker : Lesly-Ann Daniel - EURECOM
Microarchitectural optimizations, such as caches and speculative out-of-order execution, are essential for achieving high performance. However, these same mechanisms also open the door to attacks that can undermine software-enforced security policies. The current gold standard for defending against such attacks is the constant-time programming discipline, which prohibits secret-dependent control[…]-

Blockchain and digital currencies: between European regulation and technological challenges
Speaker : Loïc Miller - CentraleSupélec
As the European Union develops a legal framework for crypto-assets and data protection, the technological question underlying the emergence of a genuine digital currency remains open. Blockchain today stands as an interdisciplinary field of study at the crossroads of computer science, economics, and law. This presentation will place the ongoing regulatory framework in perspective with the[…]-
