   This document describes how to extend the Internet Key Exchange
   Protocol Version 2 (IKEv2) to allow multiple key exchanges to take
   place while computing of a shared secret during a Security
   Association (SA) setup.  The primary application of this feature in
   IKEv2 is the ability to perform one or more post-quantum key
   exchanges in conjunction with the classical (Elliptic Curve) Diffie-
   Hellman key exchange, so that the resulting shared key is resistant
   against quantum computer attacks.  Another possible application is
   the ability to combine several key exchanges in situations when no
   single key exchange algorithm is trusted by both initiator and

   This document updates RFC7296 by renaming a tranform type 4 from
   "Diffie-Hellman Group (D-H)" to "Key Exchange Method (KE)" and
   renaming a field in the Key Exchange Payload from "Diffie-Hellman
   Group Num" to "Key Exchange Method".  It also renames an IANA
   registry for this transform type from "Transform Type 4 - Diffie-
   Hellman Group Transform IDs" to "Transform Type 4 - Key Exchange
   Method Transform IDs".  These changes generalize key exchange
   algorithms that can be used in IKEv2.
