- This paper introduces CSIDH; a new method for post-quantum key exchange based on isogenies. It is 2000 times more efficient than the previous post-quantum non-interactive key exchange; it is compatible (unlike many other proposals) with important internet protocols e.g. Google's 0-RTT QUIC protocol. The work rekindled interest in isogenies as a method for post-quantum cryptography. Although CSIDH was published after the start of the NIST post-quantum competition, its desirable properties have led Cloudflare (the world’s largest CDN) to experiment with its usage in their post quantum migration plans (https://godoc.org/github.com/cloudflare/circl). The paper won the 2019 Best Dutch Cybersecurity Paper Award (https://www.dcypher.nl/en/dutch-cyber-security-research-paper-award-2019).
