In recent work with Dat\, Helm\, and Kurinczuk\, we have shown that Langlands parameters\, when viewed through the right lens\, occur naturally within a moduli space over Z[1/p]\, and we can say some things about the geometry of this moduli space. This geometry should be reflected in the representation theory of p-adic groups\, on the other side of the local Langlands correspondence. The « local Langlands in families » conjecture describes the moduli space of Langlands parameters in terms of the center of the category of representations of the p-adic group– it was established for GL(n) in 2018. The goal of the talk is to give an overview of this picture\, including current work in-progress\, with some discussion of the relation with recent work of Zhu and Fargues-Scholze. \n  \n[Horaire spécial : 15h  — Exposé en ligne\, contacter l’organisateur LP pour recevoir les codes de connexion] \nVidéo et slides de l’exposé.

Think twice. \nWe uncover vulnerabilities in the OpenPGP ecosystem stemming from confusion about the definition of ElGamal encryption (and the lack of an unequivocable standard). The first vulnerability leads to practical plaintext recovery in a limited number of cases. The second one\, combined with side-channel leakage we found in some popular OpenPGP libraries\, leads to feasible key recovery\, in relatively rare cases. \nJoint work with B. Poettering and A.
