Léo Perrin
Special guest
Léo is a junior researcher (chargé de recherche) at Inria, in the Cosmiq team. Before that, he was a postdoc at DTU (Denmark), and a PhD student at the university of Luxembourg where he graduated in 2017. He works on symmetric cryptography (both designing and analysing block ciphers, hash functions, etc.), on discrete mathematics (mostly Boolean functions), and at the intersection of both (study of S-boxes). He also investigates the various standardizing processes that are used for cryptographic primitives.

Episode 2: Breaking Lightweight Symmetric Cryptography!
October 6th, 2020 | 34 mins 24 secs
cryptanalysis
Léo Perrin talks about how his team at INRIA was able to find serious breaks in the Gimli family of lightweight symmetric primitives, and why NIST's lightweight cryptography competition even matters in the first place, especially with block ciphers like AES dominating the industry.
