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 : Fixing IKE Phase 1 & 2 Authentication HASH Author(s) : T. Kivinen Filename : draft-ietf-ipsec-ike-hash-revised-02.txt Pages : 6 Date : 28-Nov-00 This document defines new method of calculating the authentication HASH of the IKE [RFC-2409] protocol. It fixes known problems with the IKE. The way the HASH is currently defined in the [RFC-2409] does not authen- ticate the generic ISAKMP [RFC-2408] header, nor does it authenticate any extra payloads inside phase 1 packets. This causes a security prob- lem when using extra payloads as already defined in the IKE and DOI [RFC-2407] (vendor ID payload, INITIAL-CONTACT notification etc). This document defines three methods how to negotiate the new HASH method. All methods tries to be backward compatible as much as possible. Only one of those methods must be selected by the working group and all the other should be removed from this document. There is also suggestion how to fix the Phase 2 authentication hashes so that they will also authenti- cate the generic ISAKMP header.

Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-ipsec-ike-hash-revised-02.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.
