Notes: Academic cryptography paper proposing two authenticated key exchange protocols built on supersingular isogenies — described by the authors as the first post-quantum one-round Diffie–Hellman-type authenticated key exchange protocols of their kind. One variant is proven secure under the quantum random oracle model; the other resists a “maximum exposure” scenario where a non-trivial combination of secret keys is revealed. Relevant background reading for the post-quantum cryptography/encryption-standards thread in this library (the NSA/mlkem TLS standards fight, CNSA 2.0, IETF modpod).
