Hi,

   I would ask to request a slot to discuss the LMS hash based signatures at the CRFG in-person meeting at Prague.  I will not be there in person, however David McGrew will be (and I'll be attending virtually).

   We have:


-          The latest version of the LMS draft: https://datatracker.ietf.org/doc/draft-mcgrew-hash-sigs/

-          A proof of security (in the Random Oracle model, where the hash compression function is considered the random Oracle): http://eprint.iacr.org/2017/553.pdf

-          A comparison of this proposal with the XMSS proposal under consideration by the CRFG: http://eprint.iacr.org/2017/349.pdf

-          A practical implementation of this draft: https://github.com/cisco/hash-sigs

Thank you!
