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.
