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 ...

Malicious KGC attacks in certificateless cryptography [PDF]

, 2006
Identity-based cryptosystems have an inherent key escrow issue, that is, the Key Generation Center (KGC) always knows user secret key. If the KGC is malicious, it can always impersonate the user.

An Efficient Heterogeneous Signcryption Scheme from Certificateless to Identity-based Cryptosystem

MATEC Web of Conferences, 2017
The heterogeneous signcryption can not only realize the confidentiality and un-forgeability of the information transmission between different public key cryptography environments, but also reduce the communication cost. The proposed scheme uses bilin-ear

Fraud Detection in Privacy Preserving Health Insurance System Using Blockchain Technology

Engineering Reports, Volume 7, Issue 8, August 2025.
A privacy‐preserving and fraud‐detection‐enabled health insurance claim system has been proposed that addresses the dual challenges of privacy preservation and fraud detection in health insurance claims. The proposed model enables both patients and healthcare providers to submit claims securely, ensuring patient anonymity while effectively detecting ...
