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.

Cryptanalysis and design of signature schemes with identity ambiguity in the standard model

Tongxin xuebao, 2011
The security and flaw of the two anonymous signature schemes called ZLW（2008） and LHMM（2009） were analyzed,where the ZLW scheme couldn’t provide signed message verifiability and the LHMM scheme couldn’t resist on the multiple-known-signature existential ...

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

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 ...

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 ...
