Description
In the recent years, formals methods for security and their associated tools have been used successfully both to find novel and complex attacks on many protocols [A] and to help in their standardization process. They however face a new challenge with the increasing probability of quantum computers coming into the real-world: we need to be able to provide guarantees against quantum attackers.In this talk, we will first present a broad overview of formal methods, outlining what is the general goal of the field and how we have strived toward it. We will then focus on the post-quantum issue by presenting the corresponding concrete challenges, and thus multiple ways current computational proofs of security (proof for any Polynomial Time Turing Machine attacker) can fail against a quantum attacker. We will then present the first-order logic over which Squirrel is built, the BC logic, and show based on the first part where it fails at post-quantum soundness. In a third part, we will finally present our contribution: how we made the logic and thus the Squirrel prover post-quantum sound. We will conclude by discussing some more general challenges the field may be facing in the coming years.[A] see, e.g., https://www.bbc.co.uk/news/technology-58719891 for a recent example[B] https://squirrel-prover.github.io/

The Battle Against Bots: Current Threats and New Directions to Counter Automated Attacks
Orateur : Elisa Chiapponi - Amadeus IT Group
In today's digital landscape, the battle between industry and automated bots is an ever-evolving challenge. Attackers are leveraging advanced techniques such as residential proxies, CAPTCHA farms, and AI-enhanced fingerprint rotations to evade detection and execute functional abuse attacks, including web scraping, denial of inventory, and SMS pumping. This talk will explore ongoing efforts[…]-

Un protocole SMPC de curation de données d'entrainement et sa fragilité aux hypothèses de sécurité...
Orateur : Marc-Olivier Killijian - Université du Québec à Montréal
... ou "Sécurité et insécurité - dans quel état j’erre, ai-je bien rangé mon modèle de sécurité ?" De nos jours, les sources de données, et leurs curateurs, sont répartis à travers le monde. Il arrive que les propriétaires de ces données souhaitent collaborer entre eux afin d’augmenter la qualité de ces données, particulièrement avant d’entrainer des modèles d’apprentissage machine.Dans cet exposé[…]-

Safety-Security Convergence of Industrial Control Systems
Orateur : Maxime Puys - Université Clermont Auvergne - IUT de Clermont-Ferrand
Industrial Control Systems (ICS) are designed to provide a service, such as power generation or water treatment, while protecting people, assets, and the environment against hazards. However, ICS now integrate Information Technology (IT) and are interconnected with the outside world such as the Internet, thereby exposing their infrastructures to cyberattacks. Cyberattacks have thus become new[…]-
