Sending zero-knowledge proofs to the future
CybersecurityTime-release cryptography is a flourishing research area with a long history and has been extensively studied. In this work, we enrich it by introducing a novel concept: a time-release zero-knowledge proof (TRZKP).

Streaming Zero-Knowledge Proofs
CoRR, 2023 We initiate the study of zero-knowledge proofs for data streams. Streaming interactive proofs (SIPs) are well-studied protocols whereby a space-bounded algorithm with one-pass access to a massive stream of data communicates with a powerful but untrusted prover to verify a computation that requires large space.

Zero-Knowledge Proof Systems for QMA [PDF]
SIAM Journal on Computing, 2016 Prior work has established that all problems in NP admit classical zero-knowledge proof systems, and under reasonable hardness assumptions for quantum computations, these proof systems can be made secure against quantum attacks. We prove a result representing a further quantum generalization of this fact, which is that every problem in the complexity ...

, 2023 AbstractZero-knowledge proofs are techniques to verify claims without revealing the information itself. In this process, a “prover” shares proof of their claim with a “verifier,” who then verifies the accuracy of the proof without learning any additional information. It does not prove things with certainty.

Zero-Knowledge Sets With Short Proofs [PDF]
IEEE Transactions on Information Theory, 2011 Zero knowledge sets (ZKS), introduced by Micali, Rabin, and Kilian in 2003, allow a prover to commit to a secret set S in a way such that it can later prove, non interactively, statements of the form x ∈ S (or x ∉ S), without revealing any further information (on top of what explicitly revealed by the inclusion/exclusion statements above) on S, not ...

Proofs, Arguments, and Zero-Knowledge
Foundations and Trends® in Privacy and Security, 2022 Interactive proofs (IPs) and arguments are cryptographic protocols that enable an untrusted prover to provide a guarantee that it performed a requested computation correctly. Introduced in the 1980s, IPs and arguments represented a major conceptual expansion of what constitutes a “proof” that a statement is true.

An Application of p-Fibonacci Error-Correcting Codes to Cryptography
Mathematics, 2021 In addition to their usefulness in proving one’s identity electronically, identification protocols based on zero-knowledge proofs allow designing secure cryptographic signature schemes by means of the Fiat–Shamir transform or other similar constructs ...

Zero-Knowledge Proof in NuLink
CoRRNuLink provides privacy-preserving technology for decentralized applications via APIs. Users can securely store its valuable data, trade with others and so on. To ensure the privacy and security of service provided by NuLink, (zero-knowledge) proof systems are necessary.
