OSPFv2 HMAC-SHA Cryptographic Authentication
RFC 5709, “OSPFv2 HMAC-SHA Cryptographic Authentication”, is a Proposed Standard document published in October 2009 by M. Bhatia, V. Manral, M. Fanto, R. White, M. Barnes, T. Li, R. Atkinson. It updates RFC 2328. It has since been updated by RFC 7474. The canonical text is published by the RFC Editor.
Abstract
This document describes how the National Institute of Standards and Technology (NIST) Secure Hash Standard family of algorithms can be used with OSPF version 2's built-in, cryptographic authentication mechanism. This updates, but does not supercede, the cryptographic authentication mechanism specified in RFC 2328. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
