Abstract
We propose GMSS, a new variant of the Merkle signature scheme. GMSS is the first Merkle-type signature scheme that allows a cryptographically unlimited (280) number of documents to be signed with one key pair. Compared to recent improvements of the Merkle signature scheme, GMSS reduces the signature size as well as the signature generation cost.

Keywords  Merkle signatures - post-quantum cryptography - SSL
