Technical Summary

   This document defines how to use the Authentication and Authorization
   for Constrained Environments (ACE) framework to distribute keying
   material and configuration parameters for secure group communication.
   Candidate group members acting as Clients and authorized to join a
   group can do so by interacting with a Key Distribution Center (KDC)
   acting as Resource Server, from which they obtain the keying material
   to communicate with other group members.  While defining general
   message formats as well as the interface and operations available at
   the KDC, this document supports different approaches and protocols
   for secure group communication.  Therefore, details are delegated to
   separate application profiles of this document, as specialized
   instances that target a particular group communication approach and
   define how communications in the group are protected.  Compliance
   requirements for such application profiles are also specified.

Working Group Summary

   No controversies. 

Document Quality

This draft in itself cannot be implemented. The API and message template
formats that it defines have to be instantiated by its profiles (such as
key-groupcomm-oscore), which can rather be implemented. The latest has been
implemented in the java ACE implementation for Californium
