IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

Lattice-Based Revocable Certificateless Signature
Symmetry, 2017 Certificateless signatures (CLS) are noticeable because they may resolve the key escrow problem in ID-based signatures and break away the management problem regarding certificate in conventional signatures. However, the security of the mostly previous CLS schemes relies on the difficulty of solving discrete logarithm or large integer factorization ...

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 ...

Certificateless Signature Scheme Based on Rabin Algorithm and Discrete Logarithm
, 2016 Certificateless signature can effectively immue the key escrow problem in the identity-based signature scheme. But the security of the most certificateless signatures usually depends on only one mathematical hard problem, which makes the signature ...

A Certificateless Ring Signature Scheme with High Efficiency in the Random Oracle Model [PDF]
, 2017 Ring signature is a kind of digital signature which can protect the identity of the signer. Certificateless public key cryptography not only overcomes key escrow problem but also does not lose some advantages of identity-based cryptography ...

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
