COM ⇒ OT

COM implies OT.

Statement

Migrated verbatim from commitment-scheme § Other results:

  • OT can be constructed from any non-trivial commitment scheme — Kil88

Notes

class: unstated: no citing page says which notion of reduction is meant. Recording a class the wiki does not state would add a claim.

Recorded during migration and not fixed — these are claims about the source text, not changes to it:

  • SUSPECTED MATHEMATICAL ERROR / INVERTED CITATION (reported, not fixed): Kilian’s ‘Founding cryptography on oblivious transfer’ proves that OT is COMPLETE for secure computation (OT ⇒ everything), not that OT can be built FROM commitments. Building OT from commitments would place OT in Minicrypt, contradicting Impagliazzo-Rudich. The edge is almost certainly reversed.
  • ‘any non-trivial commitment scheme’ is an undefined qualifier — ‘non-trivial’ is never defined on the page, so the hypothesis cannot be typed.
  • Directly contradicts the neighbouring line 63 bullet (COM from PRG/OWF) if taken at face value: it would make OT follow from OWFs.
