RFC 7748 : Elliptic Curves for Security

Ce nouveau #RFC est la description de deux courbes elliptiques largement utilisées mais qui n’avaient pas fait l’objet d’une description formelle complète : #curve25519 et #curve448. Maintenant que c’est fait, elles pourront être utilisées dans des normes Internet utilisant la #cryptographie comme TLS ou DNSSEC.

“A RIDDLE WRAPPED IN AN ENIGMA \ In August 2015 the U.S. National Security Agency (#NSA) released a major policy statement on the need for post-quantum #cryptography (PQC). This announcement will be a great stimulus to the development, standardization, and commercialization of new quantum-safe algorithms. However, certain peculiarities in the wording and timing of the statement have puzzled many people and given rise to much speculation concerning the NSA, #elliptic_curve_cryptography (#ECC), and quantum-safe cryptography. Our purpose is to attempt to evaluate some of the theories that have been proposed.”

Spoiler: after reading the very interesting and detailed paper, we still don’t know :-(
