Technical Summary

  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 the lifetime of the connections.
  Connection latching is layered on top of IPsec and does not modify
  the underlying IPsec architecture.

  Connection latching 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.

  Finally, the availability of IPsec channels will make it possible to
  use channel binding to IPsec channels.
