Hash-based signature use small private and public keys, and they have low computational cost; however, the signature values are quite large.  For this reason they might not be used for signing X.509 certificates or S/MIME messages; however, sine hash-based signature algorithms are secure even if a large-scale quantum computer is invented.  The low computational cost for signature verification makes hash-based signatures attractive in the Internet of Things environments, and the quantum resistance makes them attractive for the distribution of software updates.
> It has been suggested that the WG adopt draft-housley-cms-mts-hash-sig as the starting point for this work.  Since Russ Housley is the author of this draft, Tim Hollebeek will judge consensus for this discussion.  Please voice your support or concerns on the list.

Support adoption will review.
