IEEE 802.1 Working Group

January 19-22, 2026 Interim Session

Austin, TX, USA – Mixed Mode

Session Minutes

The Working Group (WG) Chair, Glenn Parsons, presided and had requested that any subgroup Chair in remote attendance have on-site an individual acting on their behalf as needed to help conduct proceedings in “mixed mode”, i.e. with local and remote participants.

The Recording Secretary, Jessy Rouyer, wrote and/or edited the minutes in part based on input from subgroup Chairs and their Secretaries.

Note that, throughout this document, minuted/recorded inputs from any attendee can not/shall not be assumed to represent a position of their employer or affiliated organization. Discussion points captured do not necessarily reflect the views of the presenter, discussion leader or minute taker, and do not imply consensus unless that is explicitly minuted. The content of draft standards is determined by the ballot process; other formal decisions are the subject of Working Group motions.

Agenda items and dispositions:

  1. Meeting introduction and other administrative items. The IEEE SA slides on IEEE SA Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0325-v01.pdf.

The Chair showed this presentation advising that the following, provided beforehand, applies:

  • Participant behavior shall comply with the outlined requirements;
  • IEEE SA’s Patent Policy is described in Clause 6 of the IEEE SA Standards Board Bylaws;
  • Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
  • There may be Essential Patent Claims of which IEEE is not aware. Additionally, neither IEEE, the WG, nor the WG Chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.
  • IEEE SA’s copyright policy is described in Clause 7 of the IEEE SA Standards Board Bylaws and Clause 6.1 of the IEEE SA Standards Board Operations Manual;
  • Any material submitted during standards development, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The Chair made the Call for Potentially Essential Patents thereby providing an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard: there were no responses to this Call prior to the end of the meeting.

4 Security Task Group

Between this session and the preceding session, the IEEE 802.1 Security Task Group (Security TG) held electronic meetings whose minutes are incorporated to these session minutes by reference as follows:

See section 1 for attendance and affiliation information.

Call to order Jan 21, 2026 at 10:03 CST by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes assisted by Karen Randall, Security TG Vice-Chair.

Agenda items and dispositions:

  1. Meeting introduction. The IEEE SA slides on IEEE Patent Policy and IEEE SA Copyright and Participation Policies were provided beforehand as part of MEETING INTRODUCTION” https://www.ieee802.org/1/files/public/templates/admin-TG-intro-0325-v01.pdf.

The Security TG Chair showed this presentation advising that the following, provided beforehand, applies:

  • IEEEs Patent Policy is described in Clause 6 of the IEEE SA Standards Board Bylaws;
  • Early identification of patent claims which may be essential for the use of standards under development is strongly encouraged;
  • There may be Essential Patent Claims of which IEEE is not aware. Additionally, neither IEEE, the WG, nor the WG Chair can ensure the accuracy or completeness of any assurance or whether any such assurance is, in fact, of a Patent Claim that is essential for the use of the standard under development.
  • IEEE SAs copyright policy is described in Clause 7 of the IEEE SA Standards Board Bylaws and Clause 6.1 of the IEEE SA Standards Board Operations Manual;
  • Any material submitted during standards development, whether verbal, recorded, or in written form, is a Contribution and shall comply with the IEEE SA Copyright Policy.

The Security TG Chair made the Calls for Potentially Essential Patents thereby providing an opportunity for participants to identify patent claim(s)/patent application claim(s) and/or the holder of patent claim(s)/patent application claim(s) of which the participant is personally aware and that may be essential for the use of that standard: there were no responses to these Calls prior to the end of the session.

The Security TG Chair asked participants to record their attendance in IMAT and, if they are unable to do so, to promptly provide their affiliation to the minute taker.

  1. Approval of agenda. The Security TG Chair presented the agenda as previously made available in https://1.ieee802.org/january-2026-interim-session-security-tg-agenda/

Disposition: the agenda was reviewed, discussed, and updated as recorded by these minutes.

  1. P802.1AReg Secure Device Identity – Amendment: Support for the Module-Lattice-Based Digital Signature Algorithm. P802.1AReg/D1.0 Working Group Ballot resolution.

Paul Bottorff, P802.1AReg editor, presented the initial WG ballot results (16 Approve, 3 Disapprove, 19 Abstentions, 52 Comments) in https://www.ieee802.org/1/files/private/eg-drafts/d1/802-1AReg-D1-0-pdis-v01.pdf. The ballot had passed, meeting the required 50% response rate (70%, 38 of the 54 eligible voters responded) and the 75% approval rate (83%, 16 of the 19 voting Approve or Disapprove has Approved). The P802.1AReg editor then led the resolution of comments received on https://www.ieee802.org/1/files/private/eg-drafts/d1/802-1AReg-d1-0.pdf, showing the comments in the comment resolution tool and updating the proposed dispositions as the meeting progressed.

  • Discussion:
  • [The following points are additional to those captured in the proposed or final disposition of comments.]
  • Comment resolution started.
  • 12:34 – 13:33 CST recess
  • Comment resolution continued.
  • Items can only be added to the Bibliography if they are referenced in the normative or informative text. Existing Bibliography entries need to be checked.

Disposition: Discussion to be continued in this session. Interim proposed disposition: https://www.ieee802.org/1/files/private/eg-drafts/d1/802-1AReg-D1-0-pdis-v01.pdf. The following existing items in the Bibliography are not referenced in the text and need to be removed as part of editorial corrections to existing functionality or references added where required to existing text, in either P802.1AReg or P802.1AR-2018-Rev: IEEE Std 1363-2000, IETF RFC 5246. The reference in the main text to SP 800-57 should have ‘[B12]’ (possibly renumbered) added. The existing reference [B14] for ‘BRSKI’ needs to be updated to IETF RFC 8995 (May 2021).

  1. P802.1AEef MAC Security – Amendment: Ascon Cipher Suite P802.1AEef/D0.1 Task Group Ballot Resolution.

Mick Seaman, P802.1AEef editor, presented the initial TG ballot results (5 Approve, 1 Disapprove, 7 Abstentions, with comments from 5 voters). Those results and the collected comments with some initial dispositions were available at: https://www.ieee802.org/1/files/private/ef-drafts/d0/802-1AEef-d0-1-pdis-v01.pdf. The P802.1AEef editor then led the resolution of comments received on https://www.ieee802.org/1/files/private/ef-drafts/d0/802-1AEef-d0-1.pdf, updating the proposed dispositions as the meeting progressed.

Discussion:

[The following points are additional to those captured in the proposed or final disposition of comments.]

Both sets of test vectors are in agreement. The generation of both raised the need to be clear about the endianness of the Key (SAK) as noted in comment.

Disposition: Comment resolution to be continued.

15:17 – 16:02 CST recess

Mick Seaman, IEEE 802.1 Security TG Chair, reminded the meeting that the previously presented and available IEEE SA Patent, Copyright, and Participant Behavior policies applied and repeated the Call for Patents.

  1. Any Other Business: Ethernet Link Security for Data Center Interconnect.

Mick Seaman, Security TG Chair, introduced this A.O.B. item. This followed a request from the 802.3 leadership for the 802.1 Security TG review of a proposal for new work for securing P802.3dj. The subject had been raised under A.O.B. in the Nov 2025 plenary session and additional information circulated in this Jan 2026 interim session to 802.1 and potential 802.3 participants in the discussion: https://www.ieee802.org/1/private/email2/msg38801.html

Haojie Wang presented “Discussion of Ethernet Link Security for Inter-Datacenter Interconnection” https://www.ieee802.org/1/files/public/docs2026/new-wang-inter-datacenter-sec-0126-v02.pdf.

Discussion:

  • Concern that the proposal may be duplication of work already carried out in other SDOs.
  • Slide 3 item 1 notes the expansion of 64-byte frames when protected by MACsec. However, if 64-byte frames are common they can be packed into a single frame using Mac Privacy Protection (IEEE Std 802.1AEdk-2023) as well as MACsec resulting in a bandwidth saving relative to unprotected frames (bandwidth available 130% of the unprotected case).
  • Slide 3 item 3 is incorrect in its description of MACsec relative to PFC. P802.1Qdt is addressing measurement of the headroom required for lossless PFC enable operation, while it is necessary to be clear about the placement of MACsec in the measurement path this is not a significant complication. PFC protection is desirable to guard against some potential attacks.
  • Slide 6 shows authentication frames running over the protected link. This introduces the possibility of misalignment between the two peers in their transition to using data keys or rolling over from one data key to another, requiring a recovery mechanism if the control plane is no longer (perceived to be operational). The need for such recovery would add further vulnerability to attack.
  • Slide 9 is misleading in its depiction of EAP/MKA operation as continued operation is required for reauthentication and subsequent key rollover for non-stop operation mission critical link as well as for monitoring. Dealing with control loss by dropping the link and restarting is not acceptable.
  • Slide 8. All the mechanisms proposed are at a mature/complete stage in the ITU and not new.
  • Slide 11. It is not the role of the 802.1 Security TG to tell 802.3 what to do in the MAC and PHY. The Security TG has had requests to use a single instance of MACsec over concatenated links. In a simple scenario, a simple low-level bridge (a TPMR in IEEE Std 802.1Q) can accommodate differences between media types along the link. The MACsec coverage can be extended to avoid exposure in shared/accessible equipment. High link speeds can be supported using either the parallelism naturally provided by AES GCM or by merging separately protected streams. MACsec and MKA are being used to protect Ethernet over MPLS.
  • 802.1 is sensitive to being told that standards need to change. Encrypting data is the easy part, the control part (authentication, authorization, key agreement, reauthentication, monitoring) is more challenging.
  • The type of approach advocated has been in use since 2017 in the market, standardized, and has been through the FIPS process. Optimizes for the bulk Layer 1 payload, embraced by vendors, works with a Tag (ICV) length of 128 bits. Scales well with GCM slicing. Clear text channel is provided for control/key agreement, although the key agreement protocol is not specified by the ITU.
  • GCM AES protection at the bulk payload level introduces delay equivalent to 1.2 km of fiber, acceptable in the market for data center interconnect.
  • The proposal is specifically for use from one data center to another. Within Data Center MACsec is not needed, assuming the data center is internally secure. This may not be the case for multi-tenant data centers, and even within a single operator/user data center there may be internal threats best protected against.
  • This is already mature technology. Nothing to prevent the ITU Recommendation being used in the context of P802.3dj. Prefer not to have to add to the P802.3dj standard.
  • Nothing to prevent use of the existing standardized technology in the context of the ER1 PMD. Can build using 802.3dj plus ITU Recommendations. But there are other 802.3 PMDs that do not use the same frame structure. Current technology is not really a sublayer that can be inserted into the 802.3 stack. Concern about introducing something that is too specific and of limited applicability. Not advocating fitting the same approach across the range of PMDs.

Disposition: Meeting objectives of bringing experts together to help with clarification has been met. Any further 802.1 Security Task Group activity on this subject would be at the request of 802.3.

17:12 CST recess

Call to order Jan 22, 2026 at 8:00 CST by Mick Seaman, IEEE 802.1 Security TG Chair, who presided and wrote the minutes assisted by Karen Randall, Security TG Vice-Chair, and who reminded the meeting that the previously presented and available IEEE SA Patent, Copyright, and Participant Behavior policies applied, repeated the Call for Patents, and reviewed the agenda for the morning’s meeting.

  1. MACsec over/for MPLS. Hooman Bidgoli presented “MACsec Enhanced” https://www.ieee802.org/1/files/public/docs2025/new-bidgoli-macsec-enhanced-1125-v01.pdf.

Discussion:

  • Uses MACsec engine to encrypt IP and MPLS flow.
  • Perhaps not want to modify existing standard, would prefer to create a new doc, need name other than !MACsec enhanced! to avoid deprecating existing MACsec in existing MACsec implementations
  • Must not lose sight of the fact that MACsec and MKA are used today, in a standard conformant way to protect Ethernet over MPLS. However not all customers have adopted a virtual LAN approach for their MPLS structure. Also may need to protect part of the path.
  • Thinking about coupling to MKA: identify endpoints and scope of protection
  • Technology is potentially, protecting any type of transport, can go deeper in stack to encrypt specific services.
  • Looking for the common basis going forward: a set of fields in clear (unprotected, can be modified en route) followed by Tag or field with crypto parameters (inc. counter nonce with replay protection capability) and then everything following either integrity or confidentiality protected. Is there a common structure for the generic proposal.
  • Limited number of keys and a limited amount of associated data was important for MACsec initially and some application spaces are very cost sensitive. Do not want to make an apparent shift of focus and lose that.
  • Existing technology can support thousands of VLANs encrypted with MACsec, each with own SAK.
  • Are there use cases that require two different encryptions—one for header and one for inner payload.
  • Flexibility possible, with some authenticated some encrypted.
  • Approach the idea of variable parts of the protected payload confidentiality protected with care. This has a bad historical record, with the use of the initial “confidentiality offset” being forcefully promoted, then the offset values not correctly calculated by the proponents, and as a consequence “confidentiality offset” being deliberately omitted from later standardized Cipher Suites. The idea is recurrent and repeatedly reinvented, but it is hard to get everyone on an extended path to agree is exactly what is to be protected (not open for modification) and what is to be confidential. In general a better approach is to follow the approach for EDEs (IEEE Std 802.1AEcg-2017) with forwarding (bridging) components arranged to add an unprotected VLAN Tag prior to the SecTag while the original VLAN Tag remains in the protected scope (possibly confidential). That allowed the outer VLAN Tag to be modified enroute (priority mapping, red marking) while the original VLAN Tag is delivered guaranteed unmodified. The outer VLAN Tag can multiplex services for improved privacy.
  • Authentication of an initial part of the packet for part of the path (between forwarding system authorized to modify that initial part) will still require a way of binding that part to the remainder of the frame.
  • Inevitable to have multiple levels of protection in the path.
  • A difficult vulnerability is where an attacker uses fingerprinting technology to identify frames for a single customer amongst many supported by a provider with a view to disrupting just that customer. Using MAC Privacy Protection is desirable, but doing that at low cost may require bundling services over some segment of the “end to end” protected path, thus requiring a level of protection for communication over that segment.
  • “End to end” vs “Hop by hop” a frequent mantra, but the “end to end” discussed is very rarely application instance to application instance (use TLS for this) but simply refers to the ends of the responsibility of some organization. There may be little real difference between “end to end” in that sense and “hop by hop” where the “hop” is supported by multiple physical links.

Disposition: Discussion to be continued. An updated presentation to be made available.

  1. P802.1AReg Secure Device Identity – Amendment: Support for the Module-Lattice-Based Digital Signature Algorithm. P802.1AReg/D1.0 Working Group Ballot resolution (continued).

A Working Group recirculation ballot of P802.1AReg is anticipated, following resolution of comments, with the intention of timing that ballot to close prior to the Mar 2026 IEEE 802 plenary session.

The present intent is not to conduct a further Task Group ballot of P802.1AEef, subject to resolution of comments on the initial ballot, but to seek 802.1 permission to proceed to Working Group ballot in the closing Mar 2026 IEEE 802 plenary meeting.

The Security TG will meet during the Mar 2026 IEEE 802 plenary session to be held in Vancouver, BC, Canada.

Disposition: For information.

  1. YANG 802.1 Project Status. The YANGsters Chair presented the topic by showing https://1.ieee802.org/yang-sanity/.
  • The table at “YANG Sanity” https://1.ieee802.org/yang-sanity/ provides an overview of all currently open IEEE 802.1 projects that contain or are expected to contain YANG.
  • It was discussed whether the work on MIBs ongoing in IEEE 802.1 should also be tracked the same way.
  • Currently MIBs are only provided by IEEE 802 as attachment to the published standards and through the IEEE 802.1 website at https://1.ieee802.org/mib-modules/.
  • Providing MIB modules the same way as YANG modules was discussed. Further discussion on the topic is needed.
  • MIB repositories are available on the internet, for example at https://mibs.observium.org/.

Disposition: For information.

  1. Instance Examples. The YANGsters Chair provided an overview of the topic by showing “macsec and lag” yansters-smansfield-macsec-lag-instances-0126-v01.pdf and “YANG models for Systems with Link Aggregation” https://www.ieee802.org/1/files/public/docs2025/yangsters-haddock-systems-with-LAG-1025-v2.pdf, and led the discussion.
  • The YANG tree that provides an overview of how LAG and MACSec integrate on the 802.1 bridge model, if used on the same port, was shown.
  • The question of how this integrates into the IEEE 802.11 architecture was raised.
  • It was suggested to start a discussion with the 802.11 WG on the topic.

Disposition: More discussion needed.

  • Detailed information on maintenance item 037 can be found at https://www.802-1.org/items/481.
  • The maintenance item points out that the representation of scaled-ns, uscaled-ns, and float64, as provided in ieee802-dot1as-gptp.yang, can be ambiguous and hard to handle.
  • A suggestion on how to change the representation of those types has been provided in “YANG Type Pattern Proposals for P802.1ASdn/D2.2” https://www.ieee802.org/1/files/public/docs2024/dn-specht-type-pattern-proposals-0724-v01.pdf.
