Security and Efficiency Models for Cyber-Physical Systems in Medical Devices

The article explores security and efficiency models applied in cyber-physical systems of medical devices, which are increasingly integrated into the IoT framework. It provides a detailed analysis of key threats to the confidentiality, integrity, and availability of data generated and processed by such devices, considering them as critical components of patient safety. Additionally, the article examines approaches to enhancing the efficiency of medical cyber- physical systems under constraints of limited energy consumption, low computational power, and restricted memory capacity. Solutions are proposed based on the implementation of lightweight cryptographic algorithms, such as lightweight block ciphers and digital signature algorithms, which help reduce energy consumption while ensuring a high level of security. The proposed models aim to ensure the secure processing and transmission of personal medical data, particularly in scenarios of limited network bandwidth and the need to minimize transmission delays. Moreover, the article discusses aspects of the real-time efficient operation of cyber- physical systems, which is critical for the uninterrupted and reliable functioning of medical devices. The article also includes a comparative analysis of existing protection methods and suggests new approaches to improving the overall reliability and efficiency of medical cyber-physical systems.
