Does the working group (WG) consensus represent the strong concurrence of a<br> few individuals, with others being silent, or did it reach broad agreement?<br><br>About Adoption/History: <br>Yes, it reached broad (proportional to the active users) agreement. <br><br>Proposed by Hannes and Thomas originally OCT-2018; early support with reviews from: Barry Leiba, and Loganaden Velvindron (and comment from John Mattsson). CFA on 05-2025 Supported in ML by Eric Rescorla , Martin Thomson, and Loganaden Velvindron. Michel Richardson supported and actively contributed to the draft in 04-2022, later joined as co-author in v-08 OCT-2023.<br>WGLC for draft-ietf-uta-tls13-iot-profile-13 received support from<br>Marco Tiloca (+review that led to version 14), Henk Birkholz, Rich Salz.<br><br>Daniel Migault did an extensive review of draft-ietf-uta-tls13-iot-profile-14, which led to v17 on 18th October 2025. Then, Daniel M. gave an extensive reply on 7th November 2025, which led to v18 on 4th Feb 2026, acknowledged by Daniel. v19 Daniel has been included as author of the document.<br><br><br>2. Was there controversy about particular points, or were there decisions where<br> the consensus was particularly rough?<br><br><br>None so far. <br><br>Extract from Reply from Michael Richardson [https://mailarchive.ietf.org/arch/msg/uta/0F71htIZKCwP1b96bdjOt_HrwKM/]<br>"As I recall, we made a conscious decision not to make any quantum-safe<br>recommendations."<br><br><br>3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If<br> so, please summarize the areas of conflict in separate email messages to the<br> responsible Area Director. (It should be in a separate email because this<br> questionnaire is publicly available.)<br><br>No<br><br>4. For protocol documents, are there existing implementations of the contents of<br> the document? Have a significant number of potential implementers indicated<br> plans to implement? Are any existing implementations reported somewhere,<br> either in the document itself (as [RFC 7942][3] recommends) or elsewhere<br> (where)?<br><br>N/A. It is a profile/configuration document for TLS 1.3.<br><br><br>## Additional Reviews<br><br>5. Do the contents of this document closely interact with technologies in other<br> IETF working groups or external organizations, and would it therefore benefit<br> from their review? Have those reviews occurred? If yes, describe which<br> reviews took place.<br><br>Interacts with TLS WG. <br>Further review in the form of IETF LC is sufficient.<br><br><br>6. Describe how the document meets any required formal expert review criteria,<br> such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.<br><br>N/A.<br><br><br>7. If the document contains a YANG module, has the final version of the module<br> been checked with any of the [recommended validation tools][4] for syntax and<br> formatting validation? If there are any resulting errors or warnings, what is<br> the justification for not fixing them at this time? Does the YANG module<br> comply with the Network Management Datastore Architecture (NMDA) as specified<br> in [RFC 8342][5]?<br><br>N/A.<br><br>8. Describe reviews and automated checks performed to validate sections of the<br> final version of the document written in a formal language, such as XML code,<br> BNF rules, MIB definitions, CBOR's CDDL, etc.<br><br>N/A.<br><br><br>## Document Shepherd Checks<br><br>9. Based on the shepherd's review of the document, is it their opinion that this<br> document is needed, clearly written, complete, correctly designed, and ready<br> to be handed off to the responsible Area Director?<br><br>The document is ~30 pages, well structured, clear and concise. (Of course many sections rely on background from [RFC7925], this document being an update of RFC7925, that document needs to be read before).<br><br>Introduction motivates very well the need for the TLS 1.3 update (and key differences with TLS 1.2 profile). Section 17 "Certificate Profile” (9 pages, around 30%) accounts for most of the document, understandably.<br><br>This shepherd has sent a review the 16/Feb/2026 to the ML with some nits, here: https://mailarchive.ietf.org/arch/msg/uta/apzujMfWJhuR8s3mlHCtXUmEGkI/ <br><br><br>10. Several IETF Areas have assembled [lists of common issues that their<br> reviewers encounter][6]. For which areas have such issues been identified<br> and addressed? For which does this still need to happen in subsequent<br> reviews?<br><br>No early directorate reviews were performed. The review area that is most relevant is security area. Daniel Migault gave extensive feedback on TLS-related topics. <br><br><br>11. What type of RFC publication is being requested on the IETF stream ([Best<br> Current Practice][12], [Proposed Standard, Internet Standard][13],<br> [Informational, Experimental or Historic][14])? Why is this the proper type<br> of RFC? Do all Datatracker state attributes correctly reflect this intent?<br><br>Proposed Standard. Correct status, this document updates RFC 7925 (Proposed Standard) defining TLS/DTLS 1.3 profiles for IoT devices. This is reflected on the Datatracker.<br><br>12. Have reasonable efforts been made to remind all authors of the intellectual<br> property rights (IPR) disclosure obligations described in [BCP 79][7]? To<br> the best of your knowledge, have all required disclosures been filed? If<br> not, explain why. If yes, summarize any relevant discussion, including links<br> to publicly-available messages when applicable.<br><br>All authors have confirmed publicly that they are not aware of any related IPRs:<br>https://mailarchive.ietf.org/arch/msg/uta/ItccUnHu9htDLsmi79W1I_BJJOA/<br><br>13.

Internet of Things (IoT) devices with resource constraints. This
document is a companion to RFC 7925, defining TLS/DTLS 1.3 profiles
for IoT devices. Additionally, it updates RFC 7925 with respect to
the X.509 certificate profile and ciphersuite requirements.

Among the responsibilities is<br>answering the questions in this write-up to give helpful context to Last Call<br>and Internet Engineering Steering Group ([IESG][1]) reviewers, and your<br>diligence in completing it is appreciated. The full role of the shepherd is<br>further described in [RFC 4858][2]. You will need the cooperation of the authors<br>and editors to complete these checks.<br><br>Note that some numbered items contain multiple related questions; please be sure<br>to answer all of them.<br><br>## Document History<br><br>1. Does the working group (WG) consensus represent the strong concurrence of a<br> few individuals, with others being silent, or did it reach broad agreement?<br><br>About Adoption/History: <br>Yes, it reached broad (proportional to the active users) agreement. <br><br>Proposed by Hannes and Thomas originally OCT-2018; early support with reviews from: Barry Leiba, and Loganaden Velvindron (and comment from John Mattsson). CFA on 05-2025 Supported in ML by Eric Rescorla , Martin Thomson, and Loganaden Velvindron. Michel Richardson supported and actively contributed to the draft in 04-2022, later joined as co-author in v-08 OCT-2023.<br>WGLC for draft-ietf-uta-tls13-iot-profile-13 received support from<br>Marco Tiloca (+review that led to version 14), Henk Birkholz, Rich Salz.<br><br>Daniel Migault did an extensive review of draft-ietf-uta-tls13-iot-profile-14, which led to v17 on 18th October 2025. Then, Daniel M. gave an extensive reply on 7th November 2025, which led to v18 on 4th Feb 2026, acknowledged by Daniel. <br><br><br>2. Was there controversy about particular points, or were there decisions where<br> the consensus was particularly rough?<br><br><br>None so far. <br><br>Extract from Reply from Michael Richardson [https://mailarchive.ietf.org/arch/msg/uta/0F71htIZKCwP1b96bdjOt_HrwKM/]<br>"As I recall, we made a conscious decision not to make any quantum-safe<br>recommendations."<br><br><br>3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If<br> so, please summarize the areas of conflict in separate email messages to the<br> responsible Area Director. (It should be in a separate email because this<br> questionnaire is publicly available.)<br><br>No<br><br>4. For protocol documents, are there existing implementations of the contents of<br> the document? Have a significant number of potential implementers indicated<br> plans to implement? Are any existing implementations reported somewhere,<br> either in the document itself (as [RFC 7942][3] recommends) or elsewhere<br> (where)?<br><br>N/A. It is a profile/configuration document for TLS 1.3.<br><br><br>## Additional Reviews<br><br>5. Do the contents of this document closely interact with technologies in other<br> IETF working groups or external organizations, and would it therefore benefit<br> from their review? Have those reviews occurred? If yes, describe which<br> reviews took place.<br><br>Interacts with TLS WG. <br>Further review in the form of IETF LC is sufficient.<br><br><br>6. Describe how the document meets any required formal expert review criteria,<br> such as the MIB Doctor, YANG Doctor, media type, and URI type reviews.<br><br>N/A.<br><br><br>7. If the document contains a YANG module, has the final version of the module<br> been checked with any of the [recommended validation tools][4] for syntax and<br> formatting validation? If there are any resulting errors or warnings, what is<br> the justification for not fixing them at this time? Does the YANG module<br> comply with the Network Management Datastore Architecture (NMDA) as specified<br> in [RFC 8342][5]?<br><br>N/A.<br><br>8. Describe reviews and automated checks performed to validate sections of the<br> final version of the document written in a formal language, such as XML code,<br> BNF rules, MIB definitions, CBOR's CDDL, etc.<br><br>N/A.<br><br><br>## Document Shepherd Checks<br><br>9. Based on the shepherd's review of the document, is it their opinion that this<br> document is needed, clearly written, complete, correctly designed, and ready<br> to be handed off to the responsible Area Director?<br><br>The document is ~30 pages, well structured, clear and concise. (Of course many sections rely on background from [RFC7925], this document being an update of RFC7925, that document needs to be read before).<br><br>Introduction motivates very well the need for the TLS 1.3 update (and key differences with TLS 1.2 profile). Section 17 "Certificate Profile” (9 pages, around 30%) accounts for most of the document, understandably.<br><br>This shepherd has sent a review the 16/Feb/2026 to the ML with some nits, here: https://mailarchive.ietf.org/arch/msg/uta/apzujMfWJhuR8s3mlHCtXUmEGkI/ <br><br><br>10. Several IETF Areas have assembled [lists of common issues that their<br> reviewers encounter][6]. For which areas have such issues been identified<br> and addressed? For which does this still need to happen in subsequent<br> reviews?<br><br>No early directorate reviews were performed. The review area that is most relevant is security area. Daniel Migault gave extensive feedback on TLS-related topics. <br><br><br>11. What type of RFC publication is being requested on the IETF stream ([Best<br> Current Practice][12], [Proposed Standard, Internet Standard][13],<br> [Informational, Experimental or Historic][14])? Why is this the proper type<br> of RFC? Do all Datatracker state attributes correctly reflect this intent?<br><br>Proposed Standard. Correct status, this document updates RFC 7925 (Proposed Standard) defining TLS/DTLS 1.3 profiles for IoT devices. This is reflected on the Datatracker.<br><br>12. Have reasonable efforts been made to remind all authors of the intellectual<br> property rights (IPR) disclosure obligations described in [BCP 79][7]? To<br> the best of your knowledge, have all required disclosures been filed? If<br> not, explain why. If yes, summarize any relevant discussion, including links<br> to publicly-available messages when applicable.<br><br>All authors have confirmed publicly that they are not aware of any related IPRs:<br>https://mailarchive.ietf.org/arch/msg/uta/ItccUnHu9htDLsmi79W1I_BJJOA/<br><br>13. Has each author, editor, and contributor shown their willingness to be<br> listed as such? If the total number of authors and editors on the front page<br> is greater than five, please provide a justification.<br><br>Yes: https://mailarchive.ietf.org/arch/msg/uta/ItccUnHu9htDLsmi79W1I_BJJOA/<br><br>14. Document any remaining I-D nits in this document. Simply running the [idnits<br> tool][8] is not enough; please review the ["Content Guidelines" on<br> authors.ietf.org][15]. (Also note that the current idnits tool generates<br> some incorrect warnings; a rewrite is underway.)<br><br>A) The document passes I-D nits with<br>Summary: 0 errors (**), 0 flaws (~~), 1 warning (==), 2 comments (--).<br>Warning:<br>== There are 4 instances of lines with non-ascii characters in the document.<br>Relevant -- comment:<br>Checking references for intended status: Proposed Standard<br>----------------------------------------------------------------------------<br> (See RFCs 3967 and 4897 for information about using normative references<br> to lower-maturity documents in RFCs)<br> -- Obsolete informational reference (is this intentional?): RFC 4210<br> (Obsoleted by RFC 9810)<br>---------<br><br>B) Review of "Content guidelines"<br>Regarding the content guidelines, the draft is appropriately named.

Will publication of this document change the status of any existing RFCs? If<br> so, does the Datatracker metadata correctly reflect this and are those RFCs<br> listed on the title page, in the abstract, and discussed in the<br> introduction? If not, explain why and point to the part of the document<br> where the relationship of this document to these other RFCs is discussed.<br><br>This document updates RFC 7925.<br>(This is reflected and discussed in abstract.
