The IESG has received a request from the Light-Weight Implementation Guidance WG (lwig) to consider the following document: - 'Minimal IKEv2' <draft-ietf-lwig-ikev2-minimal-02.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-10-02. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document describes minimal version of the Internet Key Exchange version 2 (IKEv2) protocol. IKEv2 is a component of IPsec used for performing mutual authentication and establishing and maintaining Security Associations (SAs). IKEv2 includes several optional features, which are not needed in minimal implementations. This document describes what is required from the minimal implementation, and also describes various optimizations which can be done. The protocol described here is compliant with full IKEv2 with exception that this document describes mainly shared secret authentication (IKEv2 requires support for certificate authentication in addition to shared secret authentication). This document does not update or modify RFC 7296, but provides more compact description of the minimal version of the protocol. If this document and RFC 7296 conflicts then RFC 7296 is the authoritative description. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-lwig-ikev2-minimal/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-lwig-ikev2-minimal/ballot/ No IPR declarations have been submitted directly on this I-D.
