Title : Problem and Applicability Statement for Better Than Nothing Security (BTNS)

The Internet network security protocol suite, IPsec, requires
authentication, usually of network layer entities, to enable access
control and provide security services. This authentication can be
based on mechanisms such as pre-shared symmetric keys, certificates
with associated asymmetric keys, or the use of Kerberos (via KINK).
The need to deploy authentication information and its associated
identities can be a significant obstacle to the use of IPsec.
This document explains the rationale for extending the Internet
network security protocol suite to enable use of IPsec security
services without authentication. These extensions are intended to
protect communication, providing "better than nothing security"
(BTNS). The extensions may be used on their own (this use called
Stand Alone BTNS, or SAB), or may be used to provide network layer
security that can be authenticated by higher layers in the protocol
stack (this use is called Channel-Bound BTNS, or CBB). The document
also explains situations for which use of SAB and/or CBB extensions
are applicable.
