          The lamps working group met at 11:00 on Nov 11, 2017. Jim Schaad was
          acting as chair for Russ Housley who could not be present.
          The status of the current drafts was covered, the current status are:
          draft-ietf-lamsp-rfc5280-i8n-update is waiting for the approval message
          to be sent.
          draft-ietf-lamps-rfc5750 and draft-ietf-lamps-rfc5751 are waiting on Jim
          to resolve AD comments
          draft-ietf-lamsp-iea-addresses has been scheduled on the 2018-01-11
          NEW WORK:
          The first new work item discussed was the CAA (Re)Discovery algorithm and
          was presented by PHB. In the discussion following the presentation, Jacob
          Hoffman-Andrews said that doing a scan of all of the DNAME records of 40M
          domain names and only 40 were using them and says that fixing this should
          not be a show stopper on getting the document published. In terms of
          progressing with the current document, Phillip stated that he had no
          problems with joint authorship and the sense of the room was that it made
          sense to get an RFC published that documented the errata algorithm in as
          clear of language as possible and superseded the current RFC. Following
          that it might make sense based on the usage of that algorithm to publish a
          new updated algorithm. Sean Turner stated that a requirement going forward
          was to identify a DN person to get input on the algorithm.
          A HUM established that people felt that they understood what was trying to
          be accomplished. Only a couple of people hummed on the plan moving
          forward(replace current RFC with errata version) but there were no
          The second new work item discussed dealt with adding SHAKE as a new hash
          algorithm for computing signatures in PKIX and CMS. Two presentations were
          given by Quynh Dang relating to the two documents. There was significant
          push in the room to not do the DSA versions of the SHAKE algorithms
          but only
          do RSA and ECDSA. Jim Schaad raised the question of making the SHAKE hash
          algorithm correspond closer to the length of the key rather than using a
          fixed size output. Doing so would use more of the space and might be
          useful. Spirited discussion followed with the majority expressing opinions
          that a fixed length output would be closer to what is done today and thus
          might be a better answer. The authors were advised to drop it from
          the next
          version and see what complaints arose from that decision.
          Quynh this presented about the CMS document for using SHAKE with little
          discussion following.
          In closing Jim noted that the current charter required publishing of
          documents before changes could be made. With the approval of the PKIX i18n
          update, charter discussions should start in the near future.
          The meeting was then adjourned.
