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.
