RFC 4753 ECP Groups for IKE and IKEv

This document describes new 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. Specifically, the new curve groups are based on modular arithmetic rather than binary arithmetic. These new 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.
