Towards privacy-preserving and fairness-aware federated learning framework
Speaker : Nesrine Kaaniche - Télécom SudParis
Federated Learning (FL) enables the distributed training of a model across multiple data owners under the orchestration of a central server responsible for aggregating the models generated by the different clients. However, the original approach of FL has significant shortcomings related to privacy and fairness requirements. Specifically, the observation of the model updates may lead to privacy[…]-

CHERI: Architectural Support for Memory Protection and Software Compartmentalization
Speaker : Robert Watson - University of Cambridge
CHERI is a processor architecture protection model enabling fine-grained C/C++ memory protection and scalable software compartmentalization. CHERI hybridizes conventional processor, instruction-set, and software designs with an architectural capability model. Originating in DARPA’s CRASH research program in 2010, the work has progressed from FPGA prototypes to the recently released Arm Morello[…]-

Lie algebras and the security of cryptosystems based on classical varieties in disguise
Speaker : Mingjie Chen - KU Leuven
In 2006, de Graaf et al. proposed a strategy based on Lie algebras for finding a linear transformation in the projective linear group that connects two linearly equivalent projective varieties defined over the rational numbers. Their method succeeds for several families of “classical” varieties, such as Veronese varieties, which are known to have large automorphism groups. In this talk, we[…]-

Dual attacks in code-based (and lattice-based) cryptography
Speaker : Charles Meyer-Hilfiger - Inria Rennes
The hardness of the decoding problem and its generalization, the learning with errors problem, are respectively at the heart of the security of the Post-Quantum code-based scheme HQC and the lattice-based scheme Kyber. Both schemes are to be/now NIST standards. These problems have been actively studied for decades, and the complexity of the state-of-the-art algorithms to solve them is crucially[…]-

Prise de contrôle d’un infodivertissement automobile à distance
Speaker : Philippe Trebuchet, Guillaume Bouffard - ANSSI
Les véhicules connectés intègrent de nombreuses technologies de communications sans-fil à distance, comme celles exploitant les protocoles Bluetooth ou WiFi. Si le gain en confort d’utilisation et d’interaction est notable, la mise à disposition de ce type d’interfaces augmente les risques en matière de cybersécurité. Dans cet article, nous analysons l’implémentation de la pile Bluetooth embarquée[…]-

Empower New Code Citizens to Reflect and Communicate on Code Security
Speaker : Manuel Maarek - Heriot-Watt University
Creating secure software code requires software engineers to elicit and follow the security requirements of the system they are building. Software engineer teams might not have the security expertise to approach this angle of software development confidently. With the democratisation of access to software development and deployment, software are often built by developers with neither software[…] -
