I-D ACTION:draft-ietf-btns-connection-latching-01.txt

A New Internet-Draft is available from the on-line
Internet-Drafts 
directories.
This draft is a work item of the Better-Than-Nothing
Security Working Group of the IETF.

	Title		: IPsec Channels: Connection Latching
	Author(s)	: N. Williams
	Filename	: draft-ietf-btns-connection-latching-01.txt
	Pages		: 14
	Date		: 2007-3-1
	
This document specifies, abstractly, how to interface
applications
   and transport protocols with IPsec so as to create
"channels" by
   "latching" "connections" (packet
flows) to certain IPsec Security
   Association (SA) parameters for their lifetime.  This can
be used to
   protect applications against accidentally exposing live
packet flows
   to unintended peers, whether as the result of a
reconfiguration of
   IPsec or as the result of using weak peer identity to
peer address
   associations.

   Weak association of peer ID and peer addresses is at the
core of
   Better Than Nothing Security (BTNS), thus connection
latching can add
   a significant measure of protection to BTNS IPsec nodes. 
Latched
   connections also represent IPsec channels, a building
block for
   channel binding to IPsec; channel binding adds an
additional level of
   protection to applications using BTNS IPsec, and IPsec in
general.

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.
