Efficient signcryption scheme based on Cocks’ identity cryptosystem
Tongxin xuebao, 2020 Most of the existing identity-based signcryption schemes are based on bilinear or multilinear pairing operations construction.To solve the problem of low efficiency caused by complex pair operation, a new efficient signcryption scheme based on the ...

How to make unforgeable money in generalised probabilistic theories [PDF]
Quantum, 2018 We discuss the possibility of creating money that is physically impossible to counterfeit. Of course, "physically impossible" is dependent on the theory that is a faithful description of nature. Currently there are several proposals for quantum money which have their security based on the validity of quantum mechanics.

CommTLC: An Alternative to Reduce the Attack Surface of HTLCs in Lightning Networks
IET Blockchain, Volume 5, Issue 1, January/December 2025.The CommTLC scheme is secure against Fakey, Griefing and Wormhole attacks, as proven using the universal composability framework. It detects adversaries in these attacks within 112 ms for a payment path involving five users. Additionally, it outperforms recent privacy‐preserving PCN‐based solutions, MAPPCN‐OR and EAMHL+, in terms of communication and ...

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 ...

Generic Construction of Dual‐Server Public Key Authenticated Encryption With Keyword Search
IET Information Security, Volume 2025, Issue 1, 2025.In this paper, we propose a generic construction of dual‐server public key authenticated encryption with keyword search (DS‐PAEKS) from PAEKS, public key encryption, and signatures. We also show that previous DS‐PAEKS scheme is vulnerable by providing a concrete attack. That is, the proposed generic construction yields the first DS‐PAEKS schemes.

Design of Linkable Ring Signature Scheme Based on the MP‐LWE Problem and Its Application in IoV
IET Information Security, Volume 2025, Issue 1, 2025.Ensuring the information security and privacy of users in the Internet of Vehicles (IoV) is crucial for gaining user trust and promoting the application of vehicular networks. This article designs an efficient linkable ring signature (LRS) scheme on the basis of the middle‐product learning with errors (MP‐LWE) problem and applies it to vehicular ...

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.

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 ...

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
