# Collapse-binding quantum commitments without random oracles

Collapse-binding quantum commitments without random oraclesD. Unruh (Asiacrypt 2016).  [publisher's version | eprint]

Abstract: We construct collapse-binding commitments in the standard model. Collapse-binding commitments were introduced by Unruh, Computationally binding quantum commitments, 2016 to model the computational-binding property of commitments against quantum adversaries, but only constructions in the random oracle model were known.

Furthermore, we show that collapse-binding commitments imply selected other security definitions for quantum commitments, answering an open question by (Unruh 2016).
