The state of isogeny based cryptography by Luca De Feo
Are isogenies alive or dead? The joke goes they're in a superposition state. I'm going to open the box in front of your eyes and show to you the current state of isogeny based cryptography after this summer's spectacular attacks on SIDH. I will try to convince you that, despite the heavy blow, isogenies are as alive as ever and creating new heroes. I will go over the various security assumptions employed in the field, how they differ, and what interesting primitives they enable. I am confident you will walk out of the room rooting for isogenies!
Luca De Feo received his PhD from École Polytechnique (France) in 2010, with a thesis on computer algebra and computational number theory. He then joined Université de Versailles (France) in 2011 as Assistant Professor, where he kept working on computer algebra and cryptography. He is currently employed at IBM Research, where he works on post-quantum cryptography and related topics.
