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.

4 Security Task Group

Between this session and the preceding session, the IEEE 802.1 Security Task Group (Security TG) did not hold electronic.

See section 1 for attendance and affiliation information.

Call to order May 14, 2026 at 13:30 CEST 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 SA Patent Policy, Copyright Policy, and Participation Behavior – Individual Method (“Policies”) were provided beforehand as part of “MEETING INTRODUCTION” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0326-v01.pdf.

The Security TG 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 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.

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

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

3. P802.1AReg Secure Device Identity – Amendment: Support for the Module-Lattice-Based Digital Signature Algorithm. Since the SA Ballot had not concluded resolution of ballot comments would be deferred to a future electronic meeting.

4. P802.1AEef MAC Security – Amendment: Ascon Cipher Suite. P802.1AEef/D1.0 Working Group Ballot Resolution. The WG ballot had passed (100% Approval with 55% Response rate). Mick Seaman, P802.1AEef Editor, presented a preliminary proposed disposition https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0-pdis-v00.pdf of the comments received on https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0.pdf and an Editor’s draft, D1.1, https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-1.pdf, with potential details for comment resolution, and led a discussion of each of the comments, updating the proposed dispositions on screen.

15:26 CEST recess

Call to order May 13, 2026 at 16:00 CEST by the Security TG Chair, who reminded the meeting that the previously presented and available IEEE SA Patent, Copyright, and Participant Behavior policies applied and repeated the Call for Patents.

4. P802.1AEef MAC Security – Amendment: Ascon Cipher Suite. P802.1AEef/D1.0 Working Group Ballot Resolution (continued). Mick Seaman, P802.1AEef Editor, led the continued discussion of the preliminary proposed disposition of the comments received on https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0.pdf.

Discussion:

  • Noted an additional comment from Don Fedyk, initially missed due to the ballot responses subject “Approve” rather than “Approved (with comments)”. Added to the set of comments and discussed.

Disposition: Discussion to be continued.

5. MACsec over/for MPLS. Mick Seaman presented “MAC Data Security” https://www.ieee802.org/1/files/public/docs2026/new-seaman-mac-data-security-0526-v00.pdf.

Discussion:

  • Presentation provides a brief recap of the protection and associated fields provided by MACsec, noting that additional frame/packet fields could be added/removed after/before protection/validation, and 802.1AE shows the DA and SA fields separately from the secured data to emphasize that. “MAC Data Security” proposes the creation of Cipher Suites that omit DA and SA protection to allow protection of the MSDU (frame data) carried over transports that change the MAC Addresses in addition to those (like the simple MAC or Virtual LAN over the WAN) that preserved those unchanged between peers.
  • SecTAG unchanged, except for the MACsec EtherType, which would reflect protocol identification suitable for the particular transport.
  • MACsec Key Agreement (MKA) unchanged or with minor additions (t.b.d.)

Disposition: Discussion to be continued.

17:19 CEST recess

Call to order May 14, 2026 at 13:30 CEST by the Security TG Chair, who reminded the meeting that this session required payment of a registration fee, showed the “MEETING INTRODUCTION” slides https://www.ieee802.org/1/files/public/templates/admin-TG-intro-0326-v01.pdf, made the call for patents, and reviewed the agenda.

6. P802.1AEef MAC Security – Amendment: Ascon Cipher Suite. P802.1AEef/D1.0 Working Group Ballot Resolution (continued). Mick Seaman, P802.1AEef Editor, presented an updated proposed disposition https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0-pdis-v02.pdf of comments (received on https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0.pdf) incorporating the updates made in the Wednesday meeting and off-line updates reflecting that meeting’s discussion, and led a TG discussion and update of each of the received comments.

Disposition:

7. MACsec over/for MPLS (continued). The Security TG Chair led a continuation of the May 13, 2026 meeting discussion, focused on the “MAC Data Security” proposal.

Discussion:

  • Discussion centered on nonce construction and scaling requirements.
  • Nonce uniqueness is required amongst all participants using the same SAK (data key). The SAK and nonce space in (possible) current use by each participant (instance of a crypto engine) identified by the SCI (Secure Channel Identifier, in the SecTAG) and the AN (Association Number, also in the SecTAG, which MACsec Key Agreement protocol maps to the Key Number for the CA—Connectivity Association for participants using the same SAK). A given system can be expected to participate in multiple P2P CAs (point to point CAs, each securing connectivity to a single peer participant) and/or multiple P2MP (point to multipoint) and/or multiple group CAs.
  • The SCI is expected, therefore, to always be present in the SecTAG, although a transport specific option might derive the SCI from transport fields expected to be known to both transmitting and receiving participants, just as MACsec can derive the SCI from the MAC SA (for a single CA for a given MAC Address).
  • A given system can use a single MAC Address to generate 2^16 SCIs, but is not constrained to a single MAC Address. The MAC Address component of the SCI can be randomly generated. The key agreement protocol is responsible for ensuring that no two participants using the same SAK use the same SCI. SAKs are not shared across CAs. The practical number of CAs/SAs (secure associations) will be limited by per SAK overhead (including key expansion for cryptographic efficiency, not by the SCI space).
  • A GCM AES XPN Cipher Suite is expected to be of primary interest. The 96-bit GCM nonce should be generated, as per the existing GCM XPN Cipher Suites, using a 32-bit SSCI (for each participant) derived from the SCI by Key Agreement protocol rule (or possibly by explicit assignment) in conjunction with the 64-bit extended packet number (and existing Salt).
  • A potential Ascon Cipher Suite would use a 128-bit nonce as per P802.1AEef/D1.0 https://www.ieee802.org/1/files/private/ef-drafts/d1/802-1AEef-d1-0.pdf with (SCI, nonce, and Salt).

Disposition:

  • Request WG authorization in the Jul 2026 plenary session to develop a PAR for ‘MAC Data Security’ along the lines of the presentation during the Sep 2026 interim session, for pre-circulation to the LMSC in the Nov 2026 IEEE 802 plenary session.
  • Further contributions solicited.

8. MKA optimization. No Contributions or further discussion at this meeting.

9. Any Other Business. No other business was discussed by the Security TG at this session.

10. Future meetings/teleconferences. Agreed (informally, none dissenting) to hold electronic meetings at 12:00 ET on Thursday May 28, June 4, and June 11, 2026 to resolve comments on the Initial SA Ballot of P802.1AReg/D1.0 and to complete the resolution of the Working Group Ballot of P802.1AEef/D1.0, with the possibility of further electronic meetings subject to the usual notice requirements.

The Security TG will meet with in-person and remote attendance during the Jul 2026 IEEE 802 plenary session in Montreal, QC, Canada and during the IEEE 802.1/802.3 interim session in Lisbon, Portugal, but not in-person during the Nov 2026 IEEE 802 plenary session in Bangkok, Thailand.
