Isogeny-Based Cryptography Tutorial : cryptography

By ISARA Corporation August 1, 2019 Isogeny-based cryptography is one of the most promising areas of quantum-safe cryptography, but it is also the most mathematically difficult to understand. In addition, since the main algorithm we will discuss—Supersingular Isogeny-based Diffie-Hellman (SIDH)—is less than a decade old, there is very little introductory material describing the fundamental concepts. […]

Part of our mission at ISARA is to educate and raise awareness of the security risks introduced by large-scale quantum computing. Since I joined ISARA in 2016, I’ve spoken to individuals, enterprises, and governments around the world, and along the way, I’ve heard some incorrect assumptions about the impact of the quantum threat and what can be done about it today.
