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:

The table in section 1 reflects the attendance and affiliation of all participants in all 802.1 WG and subgroup meetings held in this session.

Call to order May 10, 2022 at 11:00 ET 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” http://www.ieee802.org/1/files/public/templates/admin-TG-intro-0721-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;

  1. Approval of agenda. The Security TG Chair presented the agenda in https://1.ieee802.org/may-2022-interim-session-electronic-security-tg-agenda/

Discussion:

  • Under agenda item 4. Any Other Business, there will be a presentation from the proponents of the proposed P1943 PAR (Project Authorization Request) for “Standard for Post-Quantum Network Security” in the Thursday May 12, 2022 meeting. The (draft) minutes of the last Security TG meeting summarize discussion of this topic at that meeting. References that may be of interest are Kampanakis, Panburana, Daw, and Van Geest “The Viability of Post-Quantum X.509 Certificates” https://eprint.iacr.org/2018/063.pdf and Sikederis, Kampanakis, Devetsikiotis “Post-Quantum Authentication in TLS- A Performance Study” https://www.ndss-symposium.org/wp-content/uploads/2020/02/24203.pdf: these precede the current round of NIST evaluation, so their conclusions may be dated, however Falcon (at least) is a 3rd round finalist.

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

  1. P802.1AEdk MAC Privacy protection. The Security TG Chair summarized the results of the WG ballot on https://www.ieee802.org/1/files/private/dk-drafts/d2/802-1AEdk-d2-0.pdf:

Don Fedyk, P802.1AEdk Editor, led the discussion of proposed comment dispositions.

Disposition: To be continued.

13:00 ET recess

Call to order May 12, 2022 at 11:04 ET by Mick Seaman, IEEE 802.1 Security TG Chair.

  1. Any Other Business

4.1 Proposed P1943 “Standard for Post-Quantum Network Security”. Jonathan Attia and Ludovic Perret (proposed P1943 Chair & Vice-Chair, respectively) presented “IEEE P1943 (deferred) QuNET/WG” https://www.ieee802.org/1/files/public/docs2022/new-attia-p1943-deferred-discusssion-0522-v01.pdf.

Discussion:

  • IETF and IRTF coordination considered.
  • Original proposal considered by NesCom April 27, 2022 stated “The Security Task Group of the 802.1 Working Group does not consider quantum-resistant cryptography in network security protocols”.
  • IEEE Std 802.1AE (MACsec) and IEEE Std 802.1X MACsec Key Agreement (MKA) use symmetric key cryptography and supported current NIST/NSA recommendations for quantum resistant 256-bit symmetric keys from 2011 and 2010 respectively.
  • IEEE Std 802.1AR Secure Device Identity uses asymmetric keys in X.509 certificates and is planned to adopt NIST recommendations for those certificates when NIST public review completes (anticipated 2024).

Standard was restructured (802.1AR-2018) to ease addition of future cipher suites, so anticipate rapid incorporation of NIST recommendation when final.

  • IEEE 802.1 expects to defer to IEEE 802.11 and IETF for post-quantum updates to EAP (Extensible Authentication Protocol), though expects those updates to be less urgent than post-quantum updates for end-to-end protocols such as TLS, since the recording of sessions for future quantum computer analysis of 802.1X/EAP dialogue would only reveal network access information and not the application dialogue if the latter was post-quantum protected.
  • Update to proposed PAR stating that 802.1 does consider post-quantum requirements desired.
  • How much coordination and liaison is needed? Draft sharing (when draft available).
  • What is the role of an IEEE standard in this area?
  • P1943 proponents to rework proposal, clarifying final product and how it fits into the standards space, also updating information on related standards and coordination.

Disposition: Looking forward to future discussion.

  1. P802.1AEdk MAC Privacy protection (continued). Don Fedyk, P802.1AEdk Editor, led the continued discussion of proposed comment dispositions for the WG ballot on https://www.ieee802.org/1/files/private/dk-drafts/d2/802-1AEdk-d2-0.pdf.

Disposition: To be continued.

  1. A.O.B (Any other business)

6.1 MACsec and T1S. The Security TG Chair led a brief discussion of the use of MACsec with 802.3 T1S.

Discussion:

  • This issue had been raised previously, November 2011.
  • Need to record prior determination that MACsec can be used with T1S, and supports shared media, multipoint, and point-to-multipoint as well as point-to-point.

Disposition: Item closed.

  1. Future meetings. Agreed (informally, none dissenting) to hold an electronic meeting May 24 11:00-13:00 ET, to discuss P802.1Qdt (PFC enhancements) and to continue P802.1AEdk/D2.0 WG ballot comment resolution.

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

  • 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 YANGsters 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 YANGsters Chair presented the agenda in https://1.ieee802.org/may-2022-interim-session-electronic-yangsters-agenda/.

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

  1. Introduction to YANGsters. The YANGsters Chair introduced YANGsters by presenting:

Disposition: For information.

  1. Update on YANG Projects: Qcw-QRev issue. The YANGsters Chair presented “Qcw related Maintenance Items” https://www.ieee802.org/1/files/public/docs2022/yangsters-smansfield-yang-rollups-0522-v01.pdf and led the discussion.
  • Currently no revision control system is being leveraged to manage the merging of different YANG “branches” as YANG projects are completed.
  • P802.1Qcw implements the two maintenance items 0246 (https://www.802-1.org/items/380) and 0230 (https://www.802-1.org/items/346) in YANG modules that are also modified in P802.1Q-Rev, ieee802-dot1q-bridge.yang and ieee802-dot1q-pb.yang.

Disposition: Agreed (informally, none dissenting) that YANGsters suggest to let P802.1Q-Rev finish, then rebase ieee802-dot1q-bridge.yang and ieee802-dot1q-pb.yang in P802.1Qcw on the published versions from P802.1Q-Rev to implement the maintenance items.

  1. Update on YANG Projects: IEEE P802f YANG Update. The YANGsters Chair presented the topic and led the discussion.
  • Further discussion on P802f is planned for a future meeting of the TSN TG.

Disposition: For information.

  1. Instance file for VLAN Configuration update and discussion. Martin Mittelberger presented “YANG Instances” https://www.ieee802.org/1/files/public/docs2022/yangsters-mittelberger-YANG-instances-0522-v01.pdf and led the discussion.
  • An example structure of devices was presented and the YANG instances for this example were described.
  • It was pointed out that the instance data in the example is in the “operational” view, including a lot of information that is filled in by the system and does not have to be configured. This makes the example hard to follow.
  • It was suggested to use the “configuration” view instead to reduce the information presented in the example.

Disposition: Agreed (informally, none dissenting) that a next step could be to validate the instance data file.

  1. Q Clause Numbering (review QRev and the other Q derivatives). Paul Congdon presented the topic.
  • An overview of the process to assign and ensure consistency for the clause numbers in 802.1Q was given.
  • The clause numbers used in 802.1Q are maintained in a spreadsheet to ensure they are correct, consistent, and that new clause numbers are correctly allocated.

Disposition: Agreed (informally, none dissenting) that making the information in the spreadsheet available to the editors for information would be helpful.

  1. Results of Qdj YANG discussion topics: Transaction Locking and Use of RPCs to alleviate model locking concern. Stephan Kehrer provided an update on the topic.

Disposition: For information.

  1. Results of Qdj YANG discussion topics: Role-base security of Instances. Stephan Kehrer presented the topic and led the discussion.
  • It is possible to provide role-based access at an instance level, using the NETCONF Access Control Model (NACM).
  • The YANG model in P802.1Qdj is planned to have a structure that will allow a TSN profile, e.g., IEC/IEEE 60802, to use NACM to provide role-based security on an instance level.
  • A presentation is planned for a future YANGsters session to provide further information on how role-based security of instances and multi-tenant capability can be achieved using NACM.

Disposition: Agreed (informally, none dissenting) that more discussion is required.

  1. Open Discussion: What is new, upcoming, or topics that need investigation in the YANG area? The YANGsters Chair provided an overview of new and upcoming topics.

Disposition: For information.

  1. Topics deferred to a future meeting:
  • Updated Guidelines
  • Handling of Instance Testing
  • YANG Git Repository
