     CoAP Pub-Sub Profile for Authentication and Authorization for
                     Constrained Environments (ACE)
               draft-palombini-ace-coap-pubsub-profile-01

Abstract

   This specification defines a profile for authentication and
   authorization for publishers and subscribers in a pub-sub setting
   scenario in a constrained environment, using the ACE framework.  This
   profile relies on transport layer or application layer security to
   authorize the publisher to the broker.  Moreover, it relies on
   application layer security for publisher-broker and subscriber-broker
   communication.

1.  Introduction

   This specification defines a way to authorize nodes in a CoAP pub-sub
   type of setting, using the ACE framework [I-D.ietf-ace-oauth-authz].
   The pub-sub scenario is described in [I-D.ietf-core-coap-pubsub].

1.1.  Terminology

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   Readers are expected to be familiar with the terms and concepts
   described in [I-D.ietf-ace-oauth-authz] and
   [I-D.ietf-core-coap-pubsub].

2.  Overview

   The objective of this specification is to specify how to protect a
   CoAP pub-sub communication, as described in
   [I-D.ietf-core-coap-pubsub], using Ace framework
   ([I-D.ietf-ace-oauth-authz]) and profiles
   ([I-D.gerdes-ace-dtls-authorize], [I-D.seitz-ace-oscoap-profile]).

   The architecture of the scenario is shown in Figure 1.
