A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the IP Security Protocol Working Group of the IETF. Title : A Hybrid Authentication Mode for IKE Author(s) : M. Litvin, R. Shamir, T. Zegman Filename : draft-ietf-ipsec-isakmp-hybrid-auth-05.txt Pages : 10 Date : 10-Aug-00 This document describes a set of new authentication methods to be used within Phase 1 of the Internet Key Exchange (IKE). The proposed methods assume an asymmetry between the authenticating entities. One entity, typically an Edge Device (e.g. firewall), authenticates using standard public key techniques (in signature mode), while the other entity, typically a remote User, authenticates using challenge response techniques. These authentication methods are used to establish, at the end of Phase 1, an IKE SA which is unidirectionally authenticated. To make this IKE bi-directionally authenticated, this Phase 1 is immediately followed by an X-Auth Exchange [XAUTH]. The X-Auth Exchange is used to authenticate the remote User. The use of these authentication methods is referred to as Hybrid Authentication mode. This proposal is designed to provide a solution for environments where a legacy authentication system exists, yet a full public key infrastructure is not deployed.

A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: firstname.lastname@example.org. In the body type: "FILE /internet-drafts/draft-ietf-ipsec-isakmp-hybrid-auth-05.txt". NOTE: The mail server at ietf.org can return the document in MIME-encoded form by using the "mpack" utility. To use this feature, insert the command "ENCODING mime" before the "FILE" command. To decode the response(s), you will need "munpack" or a MIME-compliant mail reader. Different MIME-compliant mail readers exhibit different behavior, especially when dealing with "multipart" MIME messages (i.e. documents which have been split up into multiple messages), so check your local documentation on how to manipulate these messages. Below is the data which will enable a MIME compliant mail reader implementation to automatically retrieve the ASCII version of the Internet-Draft.
