NOVEL SMART AUTHENTICATION CONTROL FRAMEWORK FOR CLOUD BASED DIGITAL HEALTHCARE SYSTEM

Abstract

this paper aims to suggest a Hybrid Authentication mechanism for Digital Healthcare systems in Cloud Based Digital Healthcare scenario. The integrity and security of the authentication control is ensured by the lightweight biometric verification system coupled with the decentralized validation system based on Lightweight cryptography technology, which guarantees privacy and efficiency. A multi-layered architecture incorporating users, sensor nodes, edge gateways and a private blockchain has been devised to facilitate real-time authentication. It uses hash-based operations, nonces to derive session keys, and ensures smart contract validation to prevent common attacks like replay, impersonation, and MITM. Performance analysis shows that the solution can achieve better authentication time, lower latency and energy efficiency, which can be applied to the practical deployment of healthcare.
