ECP Groups For IKE and IKEv2

This document describes new Elliptic Curve Cryptography (ECC) groupsfor use in the Internet Key Exchange (IKE) and Internet Key Exchangeversion 2 (IKEv2) protocols in addition to previously defined groups.Specifically, the new curve groups are based on modular arithmeticrather than binary arithmetic. These new groups are defined to alignIKE and IKEv2 with other ECC implementations and standards,particularly NIST standards. In addition, the curves defined here canprovide more efficient implementation than previously defined ECCgroups. This memo provides information for the Internet community.
