  Pub-Sub Profile for Authentication and Authorization for Constrained
                           Environments (ACE)
                    draft-ietf-ace-pubsub-profile-02

Abstract

   This specification defines an application 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

   The publisher-subscriber setting allows for devices with limited
   reachability to communicate via a broker that enables store-and-
   forward messaging between the devices.  The pub-sub scenario using
