Internet Engineering Task Force (IETF) T. Kivinen Request for Comments: 6467 AuthenTec Category: Informational December 2011 ISSN: 2070-1721 Secure Password Framework for Internet Key Exchange Version 2 (IKEv2) Abstract This document defines a generic way for Internet Key Exchange version 2 (IKEv2) to use any of the symmetric secure password authentication methods. Multiple methods are already specified in other documents, and this document does not add any new one. This document specifies a way to agree on which method is to be used in the current connection. This document also provides a common way to transmit, between peers, payloads that are specific to secure password authentication methods. Status of This Memo This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.

Introduction The IPsecME working group was chartered to provide for IKEv2 ([RFC5996]) a symmetric secure password authentication protocol that supports the use of low-entropy shared secrets, and to protect against off-line dictionary attacks without requiring the use of certificates or the Extensible Authentication Protocol (EAP). There are multiple such methods, and the working group was to pick one. Unfortunately, the working group failed to pick one protocol, and there are multiple candidates going forward as separate documents. As each of those older versions of those documents used a different technique to negotiate the use of the method and also used different payload formats, it is very hard to try to make an implementation where multiple such systems could co-exist. Current document versions ([SPSK-AUTH], [PACE], and [PAKE]) use the method described in this document. This document describes IKEv2 payload formats that can be used for multiple secure password methods to negotiate and transmit data so each different method can easily co-exist in the same implementation. Kivinen Informational [Page 2] RFC 6467 Secure Password Framework for IKEv2 December 2011 This document consists of two major parts: o How to negotiate which secure password method negotiation is used. o How to transmit data, between peers, that is specific to secure password methods. The secure password methods are not usually meant to be used in the normal end user (remote access VPN) cases. In such cases, EAP-based authentication works fine, and the asymmetric nature of EAP does notShow full document text
