Episode 117: Isogenies with Luca De Feo

In this week’s episode, we take the podcast in a slightly different direction and dive into Isogenies - a topic at the cutting edge of cryptography. We look at how they are related to VDFs and randomness generation. Our guest, Luca de Feo, one of the co-inventor of SIDH, helps us get an understanding for what Isogenies - or morphisms of algebraic groups - really are.
