[Resource Topic] 2016/508: Collapse-binding quantum commitments without random oracles

Welcome to the resource topic for 2016/508

Title:
Collapse-binding quantum commitments without random oracles

Authors: Dominique Unruh

Abstract:

We construct collapse-binding commitments in the standard model. Collapse-binding commitments were introduced by Unruh (Eurocrypt 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 (Eurocrypt 2016).
