DCR ⇒ COM

DCR implies COM.

Statement

Migrated verbatim from decisional-composite-residuosity § Known Results:

  • DCR → COM (statistically hiding, computationally binding) — standard

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:

  • Marked standard; statistically hiding commitments from DCR are attributable (Damgard-Fujisaki), so the folklore exception is likely misapplied.
  • SUSPECTED IMPRECISION: the hiding/binding flavours claimed (statistically hiding, computationally binding) should be checked against the standard DCR-based construction.
  • Commitment flavour is not part of the conclusion identifier.
