Minimal Internet Key Exchange Version 2 (IKEv2) Initiator Implementation
Abstract
This document describes a minimal initiator version of the Internet
Key Exchange version 2 (IKEv2) protocol for constrained nodes. 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 that
can be done. The protocol described here is interoperable with a
full IKEv2 implementation using shared secret authentication (IKEv2
does not require the use of certificate authentication). This
minimal initiator implementation can only talk to a full IKEv2
implementation acting as the responder; thus, two minimal initiator
implementations cannot talk to each other.
This document does not update or modify RFC 7296 but provides a more
compact description of the minimal version of the protocol. If this
document and RFC 7296 conflict, then RFC 7296 is the authoritative
description.
