Certificateless Public Key Cryptography: A Research Survey

International Journal of Security and Its Applications, 2016
Certificateless Public Key Cryptography is a scheme that provides security by avoiding the key escrow and eliminating the drawback of identity-based cryptography. Several certificateless models have been proposed to enhance the efficiency and overcome adversaries attacks. In this paper, we survey various public key encryption schemes on certificateless

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 ...
