              Admin Interface for the OSCORE Group Manager
                   draft-ietf-ace-oscore-gm-admin-00

Abstract

   Group communication for CoAP can be secured using Group Object
   Security for Constrained RESTful Environments (Group OSCORE).  A
   Group Manager is responsible to handle the joining of new group
   members, as well as to manage and distribute the group key material.
   This document defines a RESTful admin interface at the Group Manager,
   that allows an Administrator entity to create and delete OSCORE
   groups, as well as to retrieve and update their configuration.  The
   ACE framework for Authentication and Authorization is used to enforce
   authentication and authorization of the Administrator at the Group
   Manager.  Protocol-specific transport profiles of ACE are used to
   achieve communication security, proof-of-possession and server
   authentication.
