Deterministic relativistic quantum bit commitment [PDF]
International Journal of Quantum Information, 2015 We describe new unconditionally secure bit commitment schemes whose security is based on Minkowski causality and the monogamy of quantum entanglement. We first describe an ideal scheme that is purely deterministic, in the sense that neither party needs to generate any secret randomness at any stage. We also describe a variant that allows the committer

Bit Commitment From Nonsignaling Correlations [PDF]
IEEE Transactions on Information Theory, 2011 Central cryptographic functionalities such as encryption, authentication, or secure two-party computation cannot be realized in an information-theoretically secure way from scratch. This serves as a motivation to study what (possibly weak) primitives they can be based on.

FaDe: A Blockchain-Based Fair Data Exchange Scheme for Big Data Sharing
Future Internet, 2019 In the big data era, data are envisioned as critical resources with various values, e.g., business intelligence, management efficiency, and financial evaluations. Data sharing is always mandatory for value exchanges and profit promotion.

Complete extension: the non-signaling analog of quantum purification [PDF]
Quantum, 2023 Deriving quantum mechanics from information-theoretic postulates is a recent research direction taken, in part, with the view of finding a beyond-quantum theory; once the postulates are clear, we can consider modifications to them. A key postulate is the

On the Impossibility of Unconditionally Secure Quantum Bit Commitment [PDF]
, 2021 Dominic Mayers veröffentlichte 1997 ein Unmöglichkeitstheorem, in welchem er zeigte, dass es keine quantenkryptographische bit-commitment Verfahren gibt, die uneingeschränkt sicher sind.

Nonclassicality without entanglement enables bit commitment [PDF]
, 2008 We investigate the existence of secure bit commitment protocols in the convex framework for probabilistic theories. The framework makes only minimal assumptions, and can be used to formalize quantum theory, classical probability theory, and a host of ...

Measurement-Device-Independent Two-Party Cryptography with Error Estimation
Sensors, 2020 We present an innovative method for quantum two-party cryptography. Our protocol introduces joint measurement and error estimation to improve the security of two-party cryptographic protocols. Our protocol removes the assumption of the attacker’s limited
