Small portable Elliptic-Curve Diffie-Hellman in C

Software for "Quantum-Resistant Cryptosystems from Supersingular Elliptic Curve Isogenies"

The security of our critical infrastructure is threatened by the advent of future quantum computers, breaking asymmetric cryptography – an essential part of our secure communication architecture. Quantum key distribution (QKD) remedies this weakness by providing a long term secure solution, safe against attacks from quantum computers.
