Abstract
We analyze the concrete security of a hash-based signature scheme described in a recent series of Internet Drafts by McGrew and Curcio. We show that an original version of their proposal achieves only a “loose” security bound, but that the latest version can be proven to have tighter security in the random-oracle model.
