        I-D Tag:    draft-ietf-ipsecme-ikev2-multiple-ke-12.txt

        URL:        https://www.rfc-editor.org/info/rfc9370

This document describes how to extend the Internet Key Exchange
Protocol Version 2 (IKEv2) to allow multiple key exchanges to take
place while computing a shared secret during a Security Association
(SA) setup.

This document utilizes the IKE_INTERMEDIATE exchange, where multiple
key exchanges are performed when an IKE SA is being established.  It
also introduces a new IKEv2 exchange, IKE_FOLLOWUP_KE, which is used
for the same purpose when the IKE SA is being rekeyed or is creating
additional Child SAs.

This document updates RFC 7296 by renaming a Transform 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.

This document is a product of the IP Security Maintenance and Extensions Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
