             Remote Procedure Call (RPC) Security Version 3
                    draft-ietf-nfsv4-rpcsec-gssv3-11

Abstract

   This document specifies version 3 of the Remote Procedure Call (RPC)
   security protocol (RPCSEC_GSS).  This protocol provides support for
   multi-principal authentication of client hosts and user principals to
   server (constructed by generic composition), security label
   assertions for multi-level and type enforcement, structured privilege
   assertions, and channel bindings.

   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

1.  Introduction and Motivation

   The original RPCSEC_GSS protocol [RFC2203] provided for
   authentication of RPC clients and servers to each other using the
   Generic Security Services Application Programming Interface (GSS-API)
   [RFC2743].  The second version of RPCSEC_GSS [RFC5403]  added support
   for channel bindings [RFC5056].
