Threshold ECDSA with an Offline Recovery Party [PDF]

Mediterranean Journal of Mathematics, 2021
A $(t,n)-$ threshold signature scheme enables distributed signing among $n$ players such that any subgroup of size $t$ can sign, whereas any group with fewer players cannot. Our goal is to produce signatures that are compatible with an existing centralized signature scheme: the key generation and signature algorithm are replaced by a communication ...

Decentralized Tele-Rehabilitation via Edge AI-Oracle Architecture for Spatiotemporal Pain Assessment

Sensors
Remote tele-rehabilitation requires objective pain assessment, but existing approaches fail in two distinct ways. Self-report scales such as the Visual Analog Scale and the Numeric Pain Rating Scale are easy to falsify, opening a special case of the ...

A Blockchain‐Based Privacy Protection Scheme for Bidding Transactions Supporting Threshold Traceability

IET Blockchain, Volume 6, Issue 1, January/December 2026.
ABSTRACT Bidding transactions are widely used in scenarios such as government procurement and corporate tendering. However, while traditional blockchain achieves transparency in transactions, it also poses a risk of sensitive information such as bidder identity, quotation, and time being leaked, thereby undermining the fairness and compliance of ...

Designated confirmer threshold signature and its applications in blockchains

Cybersecurity
The non-transferability of a designated confirmer signature scheme allows a signer to control the verification ability of a signature, hence protecting the signer’s privacy.

Lightweight Mutual Authentication in VANETs: A Software‐Defined Networking and Edge Computing Approach

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a lightweight mutual authentication protocol for VANETs that integrates SDN, edge computing, and ECC to achieve low‐latency, scalable, and privacy‐preserving vehicle communication. The proposed system reduces authentication delay and computational overhead while supporting batch verification and conditional identity traceability ...

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

IEC 62056‐Compliant Interoperable Smart Metering and Load Management for Indian Distribution Utilities

IET Energy Systems Integration, Volume 8, Issue 1, January/December 2026.
ABSTRACT Indian distribution utilities face persistent challenges such as billing inefficiencies, high aggregate technical and commercial (AT&C) losses, power theft and operational constraints. Although smart meters provide advanced monitoring capabilities, interoperability issues persist in Advanced Metering Infrastructure (AMI) due to multivendor ...

Design and Development of a Blockchain‐Enabled Decentralized Framework for Academic Microcredentials

IET Software, Volume 2026, Issue 1, 2026.
Traditional higher education faces significant challenges, including rising costs, inflexibility, and a disconnect from workforce demands, while current credentialing systems are often centralized and vulnerable to fraud. Microcredentials have emerged as a solution, yet they lack integration into formal degree pathways and face issues with recognition ...

Efficient Multiplicative-to-Additive Function from Joye-Libert Cryptosystem and Its Application to Threshold ECDSA

Proceedings of the 2023 ACM SIGSAC Conference on Computer and Communications Security, 2023
Threshold ECDSA receives interest lately due to its widespread adoption in blockchain applications. A common building block of all leading constructions involves a secure conversion of multiplicative shares into additive ones, which is called the multiplicative-to-additive (MtA) function.
