Internet Engineering Task Force (IETF) P. Eronen Request for Comments: 5998 Independent Updates: 5996 H. Tschofenig Category: Standards Track Nokia Siemens Networks ISSN: 2070-1721 Y. Sheffer Independent September 2010 An Extension for EAP-Only Authentication in IKEv2 Abstract IKEv2 specifies that Extensible Authentication Protocol (EAP) authentication must be used together with responder authentication based on public key signatures. This is necessary with old EAP methods that provide only unilateral authentication using, e.g., one- time passwords or token cards. This document specifies how EAP methods that provide mutual authentication and key agreement can be used to provide extensible responder authentication for IKEv2 based on methods other than public key signatures.

Introduction The Extensible Authentication Protocol (EAP), defined in [RFC3748], is an authentication framework that supports multiple authentication mechanisms. Today, EAP has been implemented at end hosts and routers that connect via switched circuits or dial-up lines using PPP [RFC1661], IEEE 802 wired switches [IEEE8021X], and IEEE 802.11 wireless access points [IEEE80211i]. One of the advantages of the EAP architecture is its flexibility. EAP is used to select a specific authentication mechanism, typically after the authenticator requests more information in order to determine the specific authentication method to be used. Rather than requiring the authenticator (e.g., wireless LAN access point) to be updated to support each new authentication method, EAP permits the use of a backend authentication server that may implement some or all authentication methods. Eronen, et al. Standards Track [Page 2] RFC 5998 Extension for EAP in IKEv2 September 2010 IKEv2 ([RFC4306] and [RFC5996]) is a component of IPsec used for performing mutual authentication and establishing and maintaining Security Associations (SAs) for IPsec ESP and Authentication Header (AH). In addition to supporting authentication using public key signatures and shared secrets, IKEv2 also supports EAP authentication. IKEv2 provides EAP authentication since it was recognized that public key signatures and shared secrets are not flexible enough to meet the requirements of many deployment scenarios. By using EAP, IKEv2 can leverage existing authentication infrastructure and credentialShow full document text
