Hash-based signaturesFoundations · Hash-based signatures derive their security only from hash functions, spanning stateful XMSS and LMS and the stateless NIST standard SLH-DSA.
LMS (Leighton-Micali Signature)Glossary · LMS (Leighton-Micali Signature) is a stateful hash-based signature scheme defined in RFC 8554 and approved by NIST SP 800-208 for firmware signing.
Merkle treeGlossary · A Merkle tree is a hash tree whose root commits to an entire data set, enabling compact membership proofs in hash-based signatures and blockchains.
XMSS (eXtended Merkle Signature Scheme)Glossary · XMSS is a stateful hash-based signature scheme standardized in RFC 8391 that arranges one-time keys under a Merkle tree for many signatures per key pair.
