Hash function ⇒ Hash-based signatures
Hash function implies Hash-based signatures.
Statement
Migrated verbatim from digital-signature § Hash-based signatures:
- SPHINCS+: stateless hash-based signatures; uses a hyper-tree of XMSS instances and a few-time signature at the leaves; standardized by NIST as SLH-DSA (FIPS 205); signatures are –50 KB
Notes
source: folklore: the claim carried no citation on the page it was
migrated from, and none was invented.
Recorded during migration and not fixed — these are claims about the source text, not changes to it:
- ‘xmss’ is a named concrete scheme, not a model object, and has no wiki page — the edge relates artifacts, not primitives.
- Uncited (no SPHINCS+ or XMSS reference page).
- SPHINCS+ uses XMSS-like subtrees plus FORS few-time signatures; naming the sub-object ‘xmss’ is an approximation of the real construction.
- No wiki citation (FIPS 205 named in prose only; the SPHINCS+ paper has no reference page).
- Hypotheses ‘xmss’ and ‘few-time-signature’ are concrete schemes/variants with no pages — the relation is between named artifacts, not model objects.
- Concrete size claim (–50 KB) uncited, which CLAUDE.md forbids.
