Title : The TCP Simple Authentication Option
Author(s) : J. Touch, A. Mankin
Filename : draft-touch-tcpm-tcp-simple-auth-03.txt
Pages : 29
Date : 2007-7-9
This document specifies a TCP Simple Authentication Option (TCP-SA)
which is intended to replace the TCP MD5 Signature option of RFC-2385
(TCP/MD5). TCP-SA specifies the use of stronger HMAC-based hashes and
provides more details on the association of security associations
with TCP connections. TCP-SA 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, to
support a larger set of hashes with minimal other system and
operational changes. TCP-SA requires no new option identifier, though
it is intended to be mutually exclusive with TCP/MD5 on a given TCP
connection. It can be used in the presence of NATs/NAPTs, and
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.
