RFC 10033: Hash-Based Signatures: State and Backup Management

Stateful Hash-Based Signature Schemes (Stateful HBS) such as Leighton-Micali Signature (LMS), Hierarchical Signature System (HSS), eXtended Merkle Signature Scheme (XMSS), and XMSS^MT combine Merkle trees with One-Time Signatures (OTSs) to provide signatures that are resistant against attacks using large-scale quantum computers.
