MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

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 ...

An efficient certificateless cryptography scheme without pairing

, 2013
We propose a mediated certificateless encryption scheme without pairing operations. Mediated certificateless public key encryption (mCL-PKE) solves the key escrow problem in identity based encryption and certificate revocation problem in public key ...

LIMA: Local and Lightweight Mutual Authentication for VANETs

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This work presents LIMA, a lightweight local authentication protocol for VANETs. It is a SAE J2735 compliant certificateless vehicle authentication that eliminates traditional PKI dependencies while providing geographic zone‐based security and time‐based attribute control.

Certificateless sIgncryption [PDF]

, 2008
Certificateless cryptography inherits a solution to the certificate management problem in public-key encryption from identity-based techniques, whilst removing the secret key escrow functionality inherent to the identity-based setting.

Eliminating Centralized Trust in VANETs: A Blockchain‐Assisted SSL‐PUF Authentication and Cross‐Domain Key Agreement Scheme

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.
Vehicular ad hoc networks (VANETs) enable secure vehicle‐to‐vehicle (V2V) and vehicle‐to‐infrastructure (V2I) communications but still rely heavily on centralized trusted authorities, creating scalability limitations, single‐point failures, and increased authentication latency.
