Abstract

The "Elliptic Curves for Security" document [RFC7748] describes two elliptic curves, Curve25519 and Curve448, as well as the X25519 and X448 functions for performing key agreement using Diffie-Hellman operations with these curves. The curves and functions are designed for both performance and security.
