Abstract

As smart healthcare systems emerge and evolve at a quick pace, the need for secure, efficient and intelligent healthcare information system (HIS) management solutions has risen. The conventional Radio Frequency Identification (RFID)-based healthcare systems typically have issues with secure access control, data confidentiality, transaction traceability and communication efficiency. To overcome these problems, the present paper presents an intelligent framework of RFID-based situational awareness, Trust-Based Access Control (TBAC), a lightweight authenticated encryption algorithm (ASCON) and an audit layer based on blockchain and the Osprey Optimisation Algorithm (OOA). The RFID layer enables real-time patient identification, monitoring and tracking, and the secure access of healthcare resources is enabled through TBAC with dynamic trust-based authorisation. ASCON provides lightweight authenticated encryption for ensuring the confidentiality, integrity and authenticity of healthcare information. Moreover, a blockchain-based audit layer has been added to ensure that transactions are recorded in an immutable and secure manner, allowing for the tracking of healthcare activities. Optimisation of security and communication parameters for increased authentication reliability, throughput, latency and energy efficiency is made possible with OOA. The proposed framework was tested with MIMIC-IV and RFID-ExSim datasets in different RFID deployment scenarios. The experimental results showed that the security detection rate for RFID was 99.05%, the packet delivery rate was 99.31%, the transaction success rate of blockchain was 99.8%, the latency was 14 ms, the encryption time was 82 ms, the decryption time was 71 ms, and the energy consumption was 0.052 J, all of which outperformed the existing baseline approaches in terms of security, communication efficiency, and scalability consistently. The results show that the proposed framework offers a safe, scalable, and intelligent HIS for the next-generation smart healthcare environments.
