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.Federated learning (FL) enables collaborative model training without collecting user data but faces security risks such as privacy breaches, poisoning, and free‐rider attacks. To address these challenges, we propose DRFL, a defense mechanism integrating dual encryption, reputation evaluation and blockchain to enhance security and transparency ...

On the Security of Diffie-Hellman Bits
, 2001 Boneh and Venkatesan have recently proposed a polynomial time algorithm for recovering a “hidden” element α of a finite field \(\mathbb{F}_p \) of p elements from rather short strings of the most significant bits of the remainder modulo p of αt for several values of t selected uniformly at random from \(\mathbb{F}_p^* \) We use some recent bounds of ...

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.
