Welcome to the resource topic for 2022/438

Title:
Computing isogenies between finite Drinfeld modules

Authors: Benjamin Wesolowski

Abstract:

We prove that isogenies between Drinfeld modules over a finite field can be computed in polynomial time. This breaks Drinfeld analogs of isogeny-based cryptosystems.
