NEW WORK:

The first new work item discussed was the CAA (Re)Discovery algorithm and
was presented by Phillip Hallam-Baker. 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as clear of language as possible and superseded the current RFC.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
dissenters.

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.
