Hi all,

Today, we published Special Publication (SP) 800-208, Recommendation for Stateful Hash-Based Signature Schemes on this page: https://csrc.nist.gov/publications/detail/sp/800-208/final, along with our responses to the received comments during the public comment period on the previous draft document.  This SP supplements FIPS 186 by approving the use of two stateful hash-based signature schemes: the eXtended Merkle Signature Scheme (XMSS) and the Leighton-Micali Signature system (LMS) as specified in Requests for Comments (RFC) 8391 and 8554, respectively.

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).

NIST SP 800-208 profiles LMS, XMSS, and their multi-tree variants. This profile approves the use of some but not all of the parameter sets defined in RFCs 8391 and 8554. The approved parameter sets use either SHA-256 or SHAKE256 with 192- or 256-bit outputs.

Regards,
Quynh.
