A New Internet-Draft is available from the on-line Internet-Drafts
directories.
This draft is a work item of the Open Shortest Path First IGP Working Group of the IETF.
Title : OSPF HMAC-SHA Cryptographic Authentication
Author(s) : M. Bhatia, et al.
Filename : draft-ietf-ospf-hmac-sha-01.txt
Pages : 11
Date : 2007-12-4
This document describes a mechanism for authenticating OSPF packets
by making use of the HMAC algorithm in conjunction with the SHA
family of cryptographic hash functions. Because of the way the hash
functions are used in HMAC construction, the collision attacks
currently known against SHA-1 do not apply.
This will be done in addition to the already documented
authentication schemes described in the base specification.

In the body type:
"FILE /internet-drafts/draft-ietf-ospf-hmac-sha-01.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.
