Description
Many systems work by receiving instructions and processing them: e.g., a browser receives and then displays an HTML page and executes Javascript scripts, a database receives a query and then applies it to its data, an embedded system controlled through a protocol receives and then processes a message. When such instructions depend on user input, one generally constructs them with concatenation or insertion. It can lead to injection-based attacks: when the user input modifies the query’s intended semantics and leads to a security breach. Protections do exist but are not sufficient as they never tackle the origin of the problem: the language itself. We propose a new formal approach based on formal languages to assess risk, enhance static analysis, and enable new tools. This approach is general and can be applied to query, programming, and domain-specific languages as well as network protocols. We are setting up an ANR project to go into this subject in more depth.

Les jeux vidéo de l’écran au réel : enjeux juridiques et (géo)politiques au prisme de la cybersécurité
Orateur : 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).
Orateur : 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[…]
