Elliptic Curve Groups modulo a Prime for IKE and IKEv2

Overview

RFC 5903, “Elliptic Curve Groups modulo a Prime for IKE and IKEv2”, is an Informational document published in June 2010 by D. Fu, J. Solinas. It obsoletes RFC 4753. The canonical text is published by the RFC Editor.

Abstract

This document describes three Elliptic Curve Cryptography (ECC) groups for use in the Internet Key Exchange (IKE) and Internet Key Exchange version 2 (IKEv2) protocols in addition to previously defined groups. These groups are based on modular arithmetic rather than binary arithmetic. These groups are defined to align IKE and IKEv2 with other ECC implementations and standards, particularly NIST standards. In addition, the curves defined here can provide more efficient implementation than previously defined ECC groups. This document obsoletes RFC 4753. This document is not an Internet Standards Track specification; it is published for informational purposes.
