Обосновано применение методов криптографической защиты медицинских данных, передаваемых между различными системами, приложениями и организациями здравоохранения, с целью обеспечения их конфиденциальности и целостности с учетом требований по работе с персональными данными и к врачебной тайне. Разработано программное средство, реализующее обработку информации в формате сообщений стандарта Health Level Seven, их шифрование и дешифрование. Исследованы зависимости скорости шифрования и объема выходных данных от применяемого криптографического алгоритма, что позволило обосновать выбор алгоритма, обладающего высоким быстродействием и минимальным влиянием на функционирование биотехнических систем. На основе результатов исследования по защите информации, передаваемой с использованием Health Level Seven, продемонстрирована целесообразность гибридного шифрования.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>биотехнические системы</kwd><kwd>стандарт Health Level Seven</kwd><kwd>криптография</kwd><kwd>защита персональных данных</kwd><kwd>врачебная тайна</kwd><kwd>цифровизация здравоохранения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>biotechnical systems</kwd><kwd>Health Level Seven standard</kwd><kwd>cryptography</kwd><kwd>personal data protection</kwd><kwd>medical confidentiality</kwd><kwd>digitalization of healthcare</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Магомедов, Ш.
