Ensuring the Protection of Patient Medical Data in Biotechnical Systems

Abstract

This paper examines the integration of biotechnical devices and systems into a medical information network. The use of cryptographic protection methods for medical data transferred between various systems, applications, and healthcare organizations is substantiated to ensure their confidentiality and integrity, taking into account requirements for handling personal data and medical confidentiality. A software tool has been developed that implements the processing of information in the Health Level Seven message format, as well as their encryption and decryption. The dependence of encryption speed and output data size on the cryptographic algorithm used is analyzed, allowing for the selection of an algorithm offering high performance and minimal impact on the functioning of biotechnical systems. Based on the results of the study on the protection of information transferred using Health Level Seven, the feasibility of hybrid encryption is demonstrated.
