Elliptic Curves — Still Hanging On In There in a Post-Quantum World?

Shor’s algorithm solves the discrete logarithm method used in elliptic curves, and so we need to migrate away from these. But, what’s left? Well, in the NIST competition it is mainly lattice methods that are left. But wait … there is one alternative method that might have a chance … SIKE (Supersingular Isogeny Diffie-Hellman).
