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		: Problem and Applicability Statement for Better
                           Than Nothing Security (BTNS)
 	Author(s)	: J. Touch, et al.
 	Filename	: draft-ietf-btns-prob-and-applic-00.txt
 	Pages		: 20

    The Internet network security protocol suite, IPsec, consisting of
    IKE, ESP, and AH, currently requires authentication via IKE of
    network layer entities to bootstrap security. This authentication can
    be based on mechanisms such as pre-shared symmetric keys, pre-shared
    certificates and associated asymmetric keys, or the use of Kerberos.
    The need for authentication information and its associated identities
    between network layer entities can be a significant obstacle to
    deploying network security.  This document explains the rationale for
    extending to the Internet network security suite to enable use of
    IPsec security mechanisms without full IKE authentication. These
    extensions are intended to protect communication ^better than
    nothing^ (BTNS) on their own (Stand Alone BTNS, or SAB), and may be
    useful in providing network layer security that can be authenticated
    by higher layers in the protocol stack, called Channel Bound BTNS
    (CBB). This document also explains situations in which use of SAB and
    CBB extensions are appropriate and can achieve their intended
    benefit.

Send a message to:

In the body type:
 	"FILE /internet-drafts/draft-ietf-btns-prob-and-applic-00.txt".

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.
