Algorithms for Internet Key Exchange version 1
RFC 4109, “Algorithms for Internet Key Exchange version 1”, is a Proposed Standard document published in May 2005 by P. Hoffman. It updates RFC 2409. The canonical text is published by the RFC Editor.
Abstract
The required and suggested algorithms in the original Internet Key Exchange version 1 (IKEv1) specification do not reflect the current reality of the IPsec market requirements. The original specification allows weak security and suggests algorithms that are thinly implemented. This document updates RFC 2409, the original specification, and is intended for all IKEv1 implementations deployed today. [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.
