SS ⇒ IT-PIR

SS implies IT-PIR.

Statement

Migrated verbatim from secret-sharing § Other results:

• Multi-server PIR follows directly from secret sharing by sharing the database index query — CGKS98

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:

• ‘follows directly … by sharing the database index query’ is a one-clause sketch; the non-collusion assumption on the servers (essential to multi-server PIR) is not stated as part of the claim.
