A New Internet-Draft is available from the on-line Internet-Drafts directories.
This draft is a work item of the TCP Maintenance and Minor Extensions Working Group of the IETF.
Title : The TCP Authentication Option
Author(s) : J. Touch, et al.
Filename : draft-ietf-tcpm-tcp-auth-opt-00.txt
Pages : 31
Date : 2007-11-12
This document specifies a TCP Authentication Option (TCP-AO) which is
intended to replace the TCP MD5 Signature option of RFC-2385 (TCP
MD5). TCP-AO specifies the use of stronger Message Authentication
Codes (MACs) and provides more details on the association of security
associations with TCP connections. TCP-AO assumes an external, out-
of-band mechanism (manual or via a separate protocol) for session key
establishment, parameter negotiation, and rekeying, replicating the
separation of key management and key use as in the IPsec suite. The
result is intended to be a simple modification to support current
infrastructure uses of TCP MD5, such as to protect BGP and LDP, and
to support a larger set of MACs with minimal other system and
operational changes. TCP-AO uses a new option identifier, even though
it is intended to be mutually exclusive with TCP MD5 on a given TCP
connection. It supports IPv6, and is fully compatible with
requirements under development for an update to TCP MD5.

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.
