  Introduction to Supersingular Isogeny Diffie-Hellman

  An approachable introduction to Supersingular Isogeny Diffie-Hellman (SIDH) — one of the few post-quantum key exchanges built on elliptic curves — written for an Elliptic Curve Cryptography course: its motivation, the math you need (isogenies, the j-invariant, supersingular curves), the key exchange itself, and Costello et al.'s recommended parameters. Rebuilt from the original LaTeX, led in by the post's own blurb.
