Security Transmission Control Strategy for End-to-end Network Link Layer of Medical IoT Devices

In recent years, with the deepening of healthcare reform and the rapid development of Internet of Things (IoT) technology, the Internet of Things (IoMT) has become a key force in improving the efficiency and quality of medical services. However, this trend is also accompanied by severe challenges to the security and integrity of medical data. As a core resource, the secure transmission of medical data is directly related to the protection of patient privacy and the quality of medical services. For this purpose, this article delves into the secure transmission control strategies from IoMT devices to the network link layer. In response to the widespread application of wireless sensor networks (WSNs) in IoMT, this article proposes an energy-saving security strategy, which is implemented at the link layer. By optimizing encryption algorithms and key management mechanisms, it not only ensures the security of data transmission, but also effectively reduces computational complexity and energy consumption, improving the overall practicality and efficiency of the system. The experimental results show that this strategy significantly reduces energy consumption during data transmission while maintaining sufficient security capabilities, prolongs the service life of IoMT devices, and provides medical institutions with more economical and environmentally friendly data security solutions.
