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 ...

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.

MSC: A Unique Chameleon Hash‐Based Off‐Chain Storage Framework for Metaverse Applications
International Journal of Network Management, Volume 35, Issue 1, January/February 2025.This paper presents the Metaverse Off‐chain Storage Framework based on Chameleon hash (MSC), a unique framework for decentralized systems that supports code or stored data updates without changing on‐chain data. It significantly reduces overhead compared to directly storing data within a smart contract. ABSTRACT Blockchain has evolved into a secure and

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

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 ...

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.
