1. Usable Formal Methods Proposed Research Group (UFMRG) Review 

  Stephen Farrell and Jonathan Hoyland joined the IAB to give an update 
  on the Usable Formal Methods Proposed Research Group (UFMRG).

  Formal methods were successfully used in the development of TLS 1.3, 
  but using them is difficult. UFMRG held a well-attended side meeting 
  at IETF 115, and the proposed RG formed in January 2023. The group 
  met at IETF 116, IETF 117, and IETF 118, as well as holding two 
  interim meetings. UFMRG did not meet at IETF 119 because most of 
  their participants are in North America and Europe, but they will 
  probably meet at IETF 120 and 121.

  The UFMRG wiki ( has references to 
  formal analyses of some IETF protocols (TLS, EDHOC etc). 

  UFMRG has had reasonable engagement levels so far, although 
  participation can be patchy as the time that people have to devote to 
  it changes. The current goals are to:

  1. Bring together the IETFers and the researchers studying formal 
     methods to share experience and ideas

  2. Explore strengths and limitations of formal methods for systems 
     specified in the IETF, and try improve things

  3. Explore how formal methods can be usefully incorporated into IETF 

  4. Create educational material, examples, open source software that 
     can be used by the IETFers

  5. Experiment with formal methods relevant to IETF

  6. Be a place for IETF WGs to find formal methods experts to assist 

2. A Look Back at IAB Workshops

  The IAB reviewed a document Dhruv Dhody compiled looking back at the 
  last 10 years of IAB workshops and asked how this information could 
  best be presented to the community. 

  The IAB concluded that the information in this document could divided 
  up and put into two different places: 

    • IAB Workshops Webpage ( 
      Information about what an IAB workshop is 

    • Blog Post: Highlighting IETF work that came out of IAB workshops 
      and other success stories.

  Mirja Kühlewind will work with Dhruv Dhody to come up with text for 
  the website and blog post.

3. Errata processing for RFCs about the RFC Series
