Recommendation for Stateful Hash-Based Signature Schemes



David A. Cooper, Daniel C. Apon, Quynh H. Dang, Michael S. Davidson, Morris J. Dworkin, Carl A. Miller


This recommendation specifies two algorithms that can be used to generate a digital signature, both of which are stateful hash-based signature schemes: the Leighton-Micali Signature (LMS) system and the eXtended Merkle Signature Scheme (XMSS), along with their multi-tree variants, the Hierarchical Signature System (HSS) and multi-tree XMSS (XMSSMT).
