SLAPPER: Secure Lightweight Authentication Protocol for Patient Electronic Healthcare Record in Mobile Environment

The adoption of advanced technology such as Electronic Healthcare File (eHF) in wireless networks has transformed healthcare systems, enabling accessibility and efficiency. This change has created significant security issues, especially in ensuring safeguarded remote user authentication on untrusted networks. Although numerous remote user authentication techniques have been developed, many fail to effectively tackle challenges such as privacy violations, vulnerability to malicious attacks. The current research proposes a secure lightweight user authentication protocol for patients e-record SLAPPER within healthcare systems, tackling these significant problems. The scheme enhances the security of patient identification verification and anomaly detection by utilising symmetric encryption and hash functions. Patients can obtain prompt and accessible care at home through electronic health care services. However, actions of technological forgeries risk patient's medical information. Employing suggested SLAPPER authentication Protocol is widely acknowledged as the most effective method for healthcare system to avoid attacks and the exploitation of resources. The suggested system establishes a secure framework for managing electronic healthcare information, encompassing registration, storage, retrieval, analysis, authentication, and verification operations. The proposed protocol is verified on scyther protocol and compared with existing schemes in terms of communication and computational cost.
