[Ace] Re: I-D Action: draft-ietf-ace-key-groupcomm-oscore-20.txt

[Marco Tiloca <[e-mail]>]

Hello ACE and Paul,

This latest version -20:

* Addresses the review from Deb Cooley (thanks!) received during IESG evaluation.

* It explicitly points out the possible use of CoAP Observe (RFC 7641) with the resource /ace-group/GROUPNAME/active at the Group Manager.

* Aligned with a follow-up from IANA and Esko [1], it updates the suggested values for the registrations in the "CoAP Content-Formats" IANA registry.


Obviously, the next step will be to create version -21, addressing the other reviews received during IESG evaluation.

Although I don't expect it to be ready in time for the upcoming cut-off deadline, I will be working on version -21 during the next few weeks.

Best,
/Marco

Internet-Draft draft-ietf-ace-key-groupcomm-oscore-20.txt is now available. It
is a work item of the Authentication and Authorization for Constrained
Environments (ACE) WG of the IETF.

   Title:   Key Management for Group Object Security for Constrained RESTful Environments (Group OSCORE) Using Authentication and Authorization for Constrained Environments (ACE)
   Authors: Marco Tiloca
            Francesca Palombini
   Name:    draft-ietf-ace-key-groupcomm-oscore-20.txt
   Pages:   125
   Dates:   2026-02-25

Abstract:

   This document defines an application profile of the Authentication
   and Authorization for Constrained Environments (ACE) framework, to
   request and provision keying material in group communication
   scenarios that are based on the Constrained Application Protocol
   (CoAP) and are secured with Group Object Security for Constrained
   RESTful Environments (Group OSCORE).  This application profile
   delegates the authentication and authorization of Clients, which join
   an OSCORE group through a Resource Server acting as Group Manager for
   that group.  This application profile leverages protocol-specific
   transport profiles of ACE to achieve communication security, server
   authentication, and proof of possession of a key owned by the Client
   and bound to an OAuth 2.0 access token.
