    Security of Health Applications in The Internet of Things Environment
    (University of M'Sila, 2024-07-25) Anwar Noureddine Bahache
    A biosensor serves as a conduit for transmitting diverse physiological data, including body temperature, electrocardiogram (ECG), pulse, blood pressure, electroencephalogram (EEG), and respiratory rate. This transmission occurs through Wireless Body Area Networks (WBANs) within the realm of remote patient diagnosis via the Internet of Medical Things (IoMT). However, the transfer of sensitive IoMT data via WBANs over insecure channels exposes it to numerous threats, underscoring the need for robust security measures against potential adversaries. This dissertation presents a new classification for authentication schemes based on architecture, further enhancing the landscape of secure healthcare communications. Additionally, it seeks to address security apprehensions associated with patient monitoring in healthcare systems, ensuring the requisite security and privacy standards during communication by introducing a resilient authentication framework. Consequently, it introduces a versatile and resilient post-quantum authentication framework tailored for cloud-based healthcare applications, this framework is suitable for various medical scenarios and applications, effectively countering vulnerabilities identified in recent scholarly works. Specifically crafted to thwart quantum attacks utilizing Kyber cryptosystem, this framework undergoes formal security validation using AVISPA tool, supplemented by an informal evaluation. Moreover, it includes a comparative analysis of performance and security vis-à-vis previous endeavors, showcasing the strengths and advantages of the proposed framework in both dimensions.
