Description
The Extensible Authentication Protocol (EAP) is a widely used three-party authentication framework that allows a client to connect to a wireless access point it does not share a secret with, using a mutually trusted server. EAP is often found in enterprise networks or large organizations to provide central key-management and user authentication; one prime example being the eduroam network.<br/> In this talk I'll present a provable-security analysis of the EAP framework. Additionally, I will also cover the cryptographic handshake used within the wireless IEEE 802.11 protocol (Wi-Fi), which is very often used in combination with EAP (then usually referred to as WPA2-Enterprise).

Dual attacks in code-based (and lattice-based) cryptography
Orateur : 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[…]-

Lie algebras and the security of cryptosystems based on classical varieties in disguise
Orateur : 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[…]-
