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 co...

We introduce and formally define polynomial commitment schemes, and provide two efficientconstructions. A polynomial commitment scheme allows a committer to commit to a polynomialwith a short string that can be used by a verifier to confirm claimed evaluations of the committedpolynomial. Although the homomorphic commitment schemes in the literature can be used toachieve this goa...

On the truthmaker view of ontological commitment [Heil (From an ontological point of view, 2003); Armstrong (Truth and truthmakers, 2004); Cameron (Philosophical Studies, 2008)], a theory is committed to the entities needed in the world for the theory to be made true. I argue that this view puts truthmaking to the wrong task. None of the leading accounts of truthmaking—via necessitation, superv...

Mothers who study at a higher education level face many challenges that traditional students do not. They have less time to and must negotiate their different commitments responsibilities, which includes taking care of children. This article reports on qualitative research conducted with small group mothers prestigious university in Scotland understand experiences belonging the space institutio...

In this article, we present the web of commitment methodology that allows us to specify the dialogical behavior of agents from the commitments that can be contracted between them and from the links that can exist between those commitments. At first, we present the DIAGAL agent communication language which is based on social commitments and dialogue games that are defined as structures regulatin...
