A Novel Perspective on IoT Security for Large-Scale Healthcare: Insights from the Literature

Abstract

The rapid growth of IoT technologies has significantly improved healthcare systems by enabling real-time patient monitoring and data collection, leading to better care delivery. However, this has also introduced substantial security risks, with sensitive patient data being vulnerable to unauthorized access and cyberattacks. The Internet of Things (IoT) has transformed healthcare by enabling real-time monitoring, remote diagnostics, and improved patient care. However, it introduces security, privacy, and scalability challenges that threaten patient safety and data integrity. The literature highlights several key strategies for improving IoT security in healthcare, including the use of ECC for lightweight encryption, ECDH for secure key exchange, and advanced authentication mechanisms. Although challenges such as device resource constraints and the need for frequent key updates remain, ongoing research continues to refine these methods, aiming to provide secure and efficient solutions for IoT-based healthcare systems.
