Hash-based signatures + Hash-based signatures ⇒ DS
Hash-based signatures together with Hash-based signatures implies DS.
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:
- No wiki citation (FIPS 205 named in prose only; the SPHINCS+ paper has no reference page).
- few-time-signature has no wiki page.
- The concrete size claim (~8-50 KB) is an uncited quantitative claim, which CLAUDE.md forbids, and the edge cannot carry it anyway.
- 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.
