IKEv2 [RFC5996] consists of the establishment of a shared secret using the Diffie-Hellman (DH) protocol, followed by authentication of the two peers. Existing implementations typically use modular exponential (MODP) DH groups, such as those defined in [RFC3526].

                     Additional Diffie-Hellman Tests         for the Internet Key Exchange Protocol Version 2 (IKEv2)


   This document adds a small number of mandatory tests required for the    secure operation of the Internet Key Exchange Protocol version 2    (IKEv2) with elliptic curve groups.  No change is required to IKE    implementations that use modular exponential groups, other than a few    rarely used so-called Digital Signature Algorithm (DSA) groups.  This    document updates the IKEv2 protocol, RFC 5996.
