Title: Isogeny based cryptography and zero-knowledge proofs of isogeny
Abstract: The talk will give an overview of isogeny-based cryptography, which is one of the popular proposals for post-quantum public-key cryptography. In particular, I will talk about the problem of proving knowledge of an isogeny. I will show an error in the De Feo-Jao-Plut sigma protocol, and explain recent joint work with De Feo, Dobson and Zobernig to fix the issue.
