Hello ACE, Like anticipated during the ACE session at the IETF 125, this latest version -04 includes:
* Clarifications largely based on comments received during the IESG evaluation of draft-ietf-ace-key-groupcomm-oscore [0] that are also applicable to the present document. * An explicit statement in Section 2 about the long-standing assumption that topic-data resources are hosted at the Broker, with different setups left out of scope for this profile. Like also discussed during the ACE session, we can wait for the publication request of the normative reference [1] to happen first, before moving the present document forward to its Shepherding phase. Best, /Marco [0] https://datatracker.ietf.org/doc/draft-ietf-ace-key-groupcomm-oscore/ [1] https://datatracker.ietf.org/doc/draft-ietf-core-coap-pubsub/ ________________________________ From: [email protected] <[email protected]> Sent: Thursday, March 19, 2026 12:28 PM To: [email protected] <[email protected]> Cc: [email protected] <[email protected]> Subject: [Ace] I-D Action: draft-ietf-ace-coap-pubsub-profile-04.txt Internet-Draft draft-ietf-ace-coap-pubsub-profile-04.txt is now available. It is a work item of the Authentication and Authorization for Constrained Environments (ACE) WG of the IETF. Title: CoAP Publish-Subscribe Profile for Authentication and Authorization for Constrained Environments (ACE) Authors: Francesca Palombini Cigdem Sengul Marco Tiloca Name: draft-ietf-ace-coap-pubsub-profile-04.txt Pages: 65 Dates: 2026-03-19 Abstract: This document defines an application profile of the Authentication and Authorization for Constrained Environments (ACE) framework, to enable secure group communication in the Publish-Subscribe (Pub-Sub) architecture for the Constrained Application Protocol (CoAP) [draft- ietf-core-coap-pubsub], where Publishers and Subscribers communicate through a Broker. This profile relies on 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. This document specifies the provisioning and enforcement of authorization information for Clients to act as Publishers and/or Subscribers, as well as the provisioning of keying material and security parameters that Clients use for protecting their communications end-to-end through the Broker. Note to RFC Editor: Please replace "[draft-ietf-core-coap-pubsub]" with the RFC number of that document and delete this paragraph.
