IEEE Access, 2020 Certificateless cryptography does not require any certificate for the public key authentication and users' public keys are transmitted with ciphertext/signatures or by making them available in the IoT-based public directory in a proper way.

Certificateless Public Key Cryptography [PDF]
, 2003 This paper introduces and makes concrete the concept of certificateless public key cryptography (CL-PKC), a model for the use of public key cryptography which avoids the inherent escrow of identity-based cryptography and yet which does not require certificates to guarantee the authenticity of public keys. The lack of certificates and the presence of an

Security-Mediated Certificateless Cryptography [PDF]
, 2006 We introduce the notion of security-mediated certificateless (SMC) cryptography. This allows more lightweight versions of mediated cryptography while maintaining the ability for instantaneous revocation of keys. Moreover, our solutions avoid key escrow, which has been used in all previous mediated cryptography algorithms. We provide a model of security

IET Blockchain, Volume 6, Issue 1, January/December 2026.ABSTRACT The proliferation of Internet of Things (IoT) devices has created an urgent demand for secure, scalable and interoperable data‐sharing architectures. Centralized paradigms exhibit single points of failure, inadequate access control and limited transparency, rendering them structurally misaligned with the distributed nature of IoT deployments ...

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a novel lightweight certificateless public key authentication with keyword search (CPAEKS) scheme tailored for IIoT environments, effectively addressing data confidentiality and retrieval efficiency. The scheme resists frequency analysis attacks, removes reliance on bilinear pairings, and eliminates key escrow and certificate ...

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 ...

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 ...
