Technical Summary

   The Internet network security protocol suite, IPsec, consisting of
   IKE, ESP, and AH, generally requires authentication of network layer
   entities to bootstrap security. This authentication can be based on
   mechanisms such as pre-shared symmetric keys, certificates and
   associated asymmetric keys, or the use of Kerberos. The need to
   deploy authentication information and its associated identities to
   network layer entities can be a significant obstacle to use of
   network security. This document explains the rationale for extending
   the Internet network security suite to enable use of IPsec security
   mechanisms without authentication. These extensions are intended to
   protect communication in a "better than nothing" (BTNS) fashion. The
   extensions may be used on their own (Stand Alone BTNS, or SAB), or
   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.
