Cryptanalysis of Two Signature Schemes for IoT-Based Mobile Payments and Healthcare Wireless Medical Sensor Networks

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.

Lightweight Mutual Authentication in VANETs: A Software‐Defined Networking and Edge Computing Approach

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 ...

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 ...

A Lightweight Polynomial–Based Provable Data Possession Scheme With Blockchain for Integrity and Ownership Verification

IET Information Security, Volume 2026, Issue 1, 2026.
Data outsourcing improves the scalability of large‐scale storage systems but introduces risks related to data tampering and unverifiable ownership claims. Existing provable data possession (PDP) schemes often incur substantial cryptographic overhead and primarily focus on data integrity.

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 ...

PQ‐AuthN‐IIoT: A Lightweight, LWE‐Based Postquantum and Privacy‐Preserving Mutual Authentication Scheme for Resource‐Constrained Industrial IoT Systems

Journal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The rapid expansion of the Industrial Internet of Things (IIoT) presents pressing challenges for secure, efficient, and privacy‐preserving communication among users, sensors, and cloud infrastructures. Existing lightweight authentication schemes, primarily based on classical cryptographic assumptions, are increasingly vulnerable to the emerging threat ...
