Symmetric private information retrieval (Single-server) ⇔ OT

Symmetric private information retrieval (Single-server) is equivalent to OT.

Statement

Migrated verbatim from single-server-private-information-retrieval:

Single-server SPIR is equivalent to -out-of- OT with an additional efficiency requirement.

Notes

source: folklore: the claim carried no citation on the page it was migrated from, and none was invented.

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:

  • MISSING CITATION for an equivalence claim.
  • ‘with an additional efficiency requirement’ means the two objects are NOT literally equivalent (SPIR = OT with sublinear communication); the qualifier makes the edge un-typeable without a quantitative field.
  • [[OT]] is a bare alias wikilink rather than the [[oblivious-transfer|OT]] form used elsewhere on the page.
