Abstract	The recent rapid digitization of healthcare settings, driven by the advancement of the Internet of Medical Things (IoMT) and full Electronic Health Records (EHRs), has increased the wireless attack surface in clinical environments exponentially. Although the Wi-Fi Protected Access 3 (WPA3) protocol has solved the most critical cryptographic flaws of its predecessor, the WPA2, the WPA3 protocol essentially is a link-layer security solution. The paper is a systematic research study investigating the structural constraints of utilizing only link-layer encryption in healthcare Wireless Local Area Networks (WLANs) and examines the urgent need to shift to application-layer End-to-End Encryption (E2EE). This report applies a multifaceted approach to literature and framework analysis to assess the performance trade-offs of using advanced application-layer encryption protocols, namely Transport Layer Security (TLS) 1.3 and Datagram TLS (DTLS) 1.3, in WPA3-Enterprise infrastructure. Moreover, the review also considers how the IEEE 2933 standard (TIPPSS framework) and the NIST SP 800-207 Zero Trust Architecture (ZTA) can be merged to create an uninterrupted cryptographic verification throughout the clinical ecosystem. Due to the extremely low computational and energy efficiency of extreme-edge IoMT devices, the study compares lightweight cryptography (LWC) that is the NIST-standardized ASCON to traditional Advanced Encryption Standard (AES) suites. The main results indicate that a defense-in-depth architecture, a synthesis of WPA3-Enterprise 192-bit mode with ASCON-based E2EE and Zero Trust micro-segmentation, is the best balance between military-grade cryptographic security and the strict latency, throughput, and battery life needs of life-critical medical telemetry systems.
