A secure Certificateless Aggregate Signature Scheme
International Journal of Security and Its Applications, 2016 Aggregate signatures allow n signatures on n distinct messages from n distinct signers to be aggregated into a single signature that convinces any verifier that n signers do indeed sign the n messages, respectively. The major advantage of utilizing aggregate signatures is to address the security of data and save bandwidth and computations in sensor ...

Cryptanalysis and Improvement of Three Certificateless Aggregate Signature Schemes [PDF]
Mathematical Problems in Engineering, 2018 The certificateless aggregate signature (CLAS) scheme is a very important data aggregation technique that compresses a large number of signatures from different users into a short signature. CLAS can reduce the total length of a signature and the computational overhead of signature verification and is therefore highly suitable for resource-constrained ...

Towards quantum‐safe blockchain: Exploration of PQC and public‐key recovery on embedded systems
IET Blockchain, Volume 5, Issue 1, January/December 2025.This paper addresses the need for quantum‐safe blockchain solutions specifically for embedded systems by integrating Post‐Quantum Cryptography (PQC) into blockchain frameworks. We propose a quantum‐secure blockchain architecture using NIST‐standardized PQC algorithms, finding Falcon‐512 to be optimal for embedded environments due to its security and ...

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

Towards secure and resilient unmanned aerial vehicles swarm network based on blockchain
IET Blockchain, Volume 4, Issue S1, Page 483-493, December 2024.Abstract Blockchain, as an emerging technology, has found diverse applications in solving trust issues in multi‐party cooperation. The field of Unmanned Aerial Vehicle (UAV) swarm networks is no exception, as UAVs are susceptible to attacks from malicious counterparts due to limited computing and storage resources. In this paper, the authors present an

Cryptanalysis of a certificateless aggregate signature scheme with efficient verification [PDF]
Security and Communication Networks, 2016 AbstractRecently, Chen et al. proposed a certificateless aggregate signature scheme with efficient verification. They claimed that their scheme could resist attacks of Type I adversary and Type II adversary. Unfortunately, we present a universal attack to demonstrate that their scheme cannot provide unforgeability.
