IOTDIR

Summary

The IOTDIR session provided an overview of the status of various IETF Working Groups (WGs) relevant to the Internet of Things (IoT) ecosystem, including updates on document progression, upcoming meetings, and new activities. A key discussion point was the ongoing progress of drafts towards Working Group Last Call (WGLC) and RFC publication across several groups. The session also included a brief update on activities in other SDOs related to IoT security and a discussion regarding meeting attendance and future scheduling.

Key Discussion Points

Review Assignments: Participants were kindly asked to promptly accept or reject draft review assignments to facilitate the review process, acknowledging the effort to assign drafts based on expertise.
IOTDIR Lunch: An IOTDIR lunch gathering with other areas is scheduled at IETF 120; participants were asked to fill out a form and inform Eric if they wish to attend.
6lo WG Update:
- Meeting in Dublin.
- One document (IPv6 ND multicast address listen registration) is in the RFC Editor Queue.
- Two drafts (Path Aware Semantic Addressing, IPv6 ND prefix registration) are advanced, updated after early reviews, and possibly nearing WGLC.
- Updates made to "Transmission of SCHC compress package over 15.4 networks" (aiming to align with the evolving SCHC architecture) and "Transmission of IPv6 packets over Optical Wireless Communications".
- One new WG document adopted: "Generic address assignment option for 6LoWPAN ND," which allows a node to request an address.
Ace WG Update: No update was provided.
Anima WG Update: Progress is slow due to complex cross-document issues with multiple documents in extended WGLCs.
ASDF WG Update:
- Meeting in Dublin.
- The core ASDF document is in AD review, with revisions underway, aiming for ISG by year-end.
- The NIPY (Non-IP device control) document was adopted in June.
- A proposal for a "digital twin" document will be discussed in Dublin, with potential adoption later this year.
- A hackathon project is planned to explore NIPY and SDF integration.
CBOR WG Update:
- Hackathon activities are planned around CBOR-related work, specifically P-CBOR implementation.
- Deterministic encoding and P-CBOR: An implementation draft is available for testing.
- EDN literals: Experienced a setback at IETF 120 due to ABNF comments, leading to significant editorial work. The document is evolving from documenting an extension to becoming a rollup specification of existing content.
- CDDL: Work on updating grammars (an AUTH48 document) is underway, preparing for a more evolutionary path towards "CDDL2". Extension points are being exercised in "CDDL Control" (submitted) and "CDDL Modules" (part of "CDDL2" evolution, currently addressing socket handling).
CoRE WG Update:
- RFC 9595 was published.
- A document on using EDHOC with CoAP and OSCORE is in AUTH48.
- Six other WG documents are in advanced stages, some approaching WGLC.
- Two new documents were adopted:
  - An ALPN ID document, instrumental for progressing DNS over CoAP.
  - CoRE CL (Corrections and Clarifications for CoAP), which consolidates reported issues and resolutions.
- Ongoing work includes group communication, OSCORE security protocol updates (key updates, proxy use), DNS over CoAP, CoAP transport indication, and CoRE CL.
- Individual submissions include CoAP over alternative transports (GATT/BLE) and a stateless variant of OSCORE.
- The WG will meet for a 2-hour session in Dublin, with additional interims planned for early next year and a one-off meeting in December, alternating with CBOR.
CoIP WG Update: No update was provided.
Delt WG Update: Information was provided in the notes (not read aloud).
IOT-OPS WG Update:
- A minor re-chartering process is active/about to start.
- The re-charter intends to expand scope to include standard track documents and a dispatch function, taking on IoT M&O related work from the OPSAREA WG.
- A re-charter proposal may be an agenda item at IETF 120.
- The WG noted a challenge with documents having high interest but relying on overloaded sole contributors, which the re-chartering aims to address.
LAKE WG Update: No update was provided.
RATS WG Update:
- A new CSR extension is being developed for remote attestation evidence (not results), allowing for heterogeneous evidence formats.
- This involves putting OIDs, including those for Conceptual Massive Repertoire (one TCG-defined, one in WGLC).
- A new ID, pkix-evidence, defines a single structure for each CBL (CBOR Layer) in RATS, enabling arbitrary statement unpacking.
- While evidence creation remains diverse, homogenization is expected at the verifier end.
- Discussion arose around an informative appendix in a CWT document about JSON for Unstructured CBOR Claim Sets, which received ISG pushback. The goal is seamless JSON/CBOR synchronization, and the informative appendix aimed to assist with this, but its inclusion remains under discussion.
ROLL WG Update:
- Meeting for one hour at IETF 120.
- RPL was submitted to the IESG, with review issues currently being addressed.
- PCH was submitted to the IESG for RFC-Editor processing.
- Enrollment Priorities is next for WGLC, with open issues nearing closure for submission.
- Work in progress includes MOPEX ND extension and ROLL Capabilities.
- Discussions are planned regarding the minimum ROO charter.
- Late update from Janos: The WGLC for the Control Plane Framework (part of the DotNet first package) is a hot topic, with positive feedback anticipated. The RAW Architecture is in its second WGLC, having undergone significant changes, and comments/updates are expected. RAW Technologies (already IETF last called) are undergoing fine-polishing. New queuing proposals and taxonomy discussions are progressing slowly at an individual contribution level, with updates expected at IETF 120.
SCHC WG Update:
- Meeting in Dublin, with several interims since the last IETF.
- Recent updates to "8824 update" and "using SCHC for compressing IPv6 headers".
- Discussions around SCHC architecture have not yet been materialized into the document.
SCHIM WG Update: No update was provided.
SKIT WG Update: No update was provided.
SMI WG Update: No update was provided.
TIPP WG Update: No update was provided.
COIN WG Update: No update was provided.
THING-TO-GROUP (T2G) / THING WG Update:
- A physical meeting will be held at IETF 120 (first in some time, with recent meetings being interims/online).
- Planned activities include discussion on the split between data and interaction models, and the close relation to ASDF work.
- Architectural aspects of security will be discussed, with close ties to work in CoRE and other IoT security groups.
- Resource Group documents are progressing slowly but steadily, with some hoped to reach last call soon.
New Activities in IoT Environments: No specific updates or comments were provided regarding new planned activities.
Other SDOs - IoT Security Foundation Update: The annual conference emphasized that device identity certificates are transitioning from optional to mandatory, prompting a focus on cost-effective and simple implementation. A marketing-heavy forum might be created to evangelize this, open to interested individuals.

Decisions and Action Items

Review Assignments: Participants are requested to accept or reject assigned draft reviews as soon as possible to ensure timely completion.
IOTDIR Lunch: Participants interested in the IOTDIR lunch at IETF 120 should fill out the provided form and inform Eric.
Meeting Attendance: To improve attendance for future IOTDIR meetings, the chairs will consider sending calendar invites and encourage participants to subscribe to the data tracker meeting calendar.

Next Steps

Working Group Meetings: Many WGs will meet physically in Dublin at IETF 120, with several planning interim meetings or one-off sessions before the next IETF.
Document Progression: Continue to drive drafts towards WGLC and RFC publication across various WGs.
IOT-OPS Re-chartering: The proposal for re-chartering IOT-OPS to expand its scope will be further discussed, potentially as an agenda item at IETF 120.
RATS Discussions: Continue discussions on CSR extensions for attestation evidence and the synchronization of JSON and CBOR structures.
ROLL WGLCs: Progress the WGLCs for the Control Plane Framework and RAW Architecture.
