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 ...

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 ...

Electronic health records (EHRs) have become a crucial application in cloud computing environments, necessitating advanced privacy‐preserving access control mechanisms. Ciphertext policy attribute‐based encryption (CP‐ABE) is a widely recognized solution for secure access control in outsourced data environments.

Fraud Detection in Privacy Preserving Health Insurance System Using Blockchain Technology
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 ...

An efficient signcryption scheme with key privacy and its extension to ring signcryption
In Information Processing Letters (2006), Tan pointed out that the anonymous signcryption scheme proposed by Yang, Wong and Deng (YWD) in ISC 2005 provides neither confidentiality nor anonymity. However, no discussion has been made on how a secure scheme can be made and there is no secure scheme available to date.

A Blockchain‐Based Certificateless Anonymous Cross‐Domain Authentication Scheme for IoV
As an essential component of the internet of things, the internet of vehicles (IoV) holds broad application prospects in areas such as safe driving, intelligent transportation, and service reservations. Due to the security and privacy requirements, anonymous authentication schemes are widely used in IoV. However, traditional certificate‐based anonymous

An efficient and secure quantum blind signature‐based electronic cash transaction scheme
The authors introduce a novel electronic cash (eCash) transaction scheme designed for quantum security, addressing weaknesses in existing models against quantum computing threats. By analysing various quantum blind signature mechanisms, the study identifies shortcomings and proposes an innovative quantum‐secure transaction framework inspired by D ...
