Quantum money with nearly optimal error tolerance
, 2016 We present a family of quantum money schemes with classical verification which display a number of benefits over previous proposals. Our schemes are based on hidden matching quantum retrieval games and they tolerate noise up to 23%, which we conjecture ...

Generic Transformation to Strongly Unforgeable Signatures [PDF]
, 2007 Recently, there are several generic transformation techniques proposed for converting unforgeable signature schemes (the message in the forgery has not been signed yet) into strongly unforgeable ones (the message in the forgery could have been signed previously). Most of the techniques are based on trapdoor hash functions and all of them require adding

Constructing Efficient Identity‐Based Signatures on Lattices
IET Information Security, Volume 2025, Issue 1, 2025.In this work, we explore the recent developments related to lattice‐based signature and preimage sampling, and specify a compact identity‐based signature (IBS) on an ideal lattice for practical use. Specifically, we first propose an ellipsoid version of the G + G signature scheme (Asiacrypt 2023) that achieves slightly better signature size and higher ...

ID-based server-aided verification signature scheme with strong unforgeability
Tongxin xuebao, 2016 Most identity-based signature schemes in the standard model are existentially unforgeable,which cannot prevent adversaries from forging valid signatures on messages that have previously been signed.However,signature verification algorithms of ID-based ...

Analysis and improvement of an identity-based signature scheme from lattices
Tongxin xuebao, 2015 Liu et al proposed an identity-based signature from lattices in 2013,and proved that it can achieve strong un-forgeability in the standard model.Through analysis,the security proof of this scheme has some defect,and then show that the scheme cannot prove

Implementation vulnerabilities in general quantum cryptography
, 2018 Quantum cryptography is information-theoretically secure owing to its solid basis in quantum mechanics. However, generally, initial implementations with practical imperfections might open loopholes, allowing an eavesdropper to compromise the security of ...

A Blockchain‐Based Certificateless Anonymous Cross‐Domain Authentication Scheme for IoV
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.As an essential component of the internet of things, the internet of vehicles (IoV) holds broad application prospects in areas such as safe driving, intelligent transportation, and service reservations. Due to the security and privacy requirements, anonymous authentication schemes are widely used in IoV. However, traditional certificate‐based anonymous

Stern–Brocot-Based Non-Repudiation Dynamic Provable Data Possession
IEEE Access, 2019 With the widespread popularity of cloud storage, cloud storage security issues have also received much attention. A provable data possession (PDP) scheme can effectively help users to verify the integrity of data stored remotely in the cloud.

Leveraging dual‐blockchain collaboration for logistics supply chain supervision
IET Blockchain, Volume 4, Issue S1, Page 570-585, December 2024.Logistics supply chains record transactions but face issues with privacy and supervision on the blockchain, a dual‐blockchain scheme is proposed with a supervision chain and management approach to enable efficient cross‐chain collaboration while preventing data leakage.
