JUSTIFICATION OF ENCRYPTION ALGORITHM FOR SYSTEMS MONITORING PERSONNEL CONDITION OF CRITICAL INFORMATIZATION OBJECTS

Abstract

The necessity of developing of systems for monitoring the physical condition of personnel at critical informatization objects is substantiated.It is shown that one ofthe technical problems that must be solved when developing such systems is ensuring the confidentiality and integrity ofinformationprocessedwithinthese systems.The solution to thisproblemis based on the selection and implementation of an encryption algorithm characterized by high performance. The encryption algorithm for systems for monitoring the physical condition of personnel at critical informatization objects must be characterized by high performance due to the need to minimize the impact of the functioning of these systems on the processes implemented within these objects. In this regard, the authors of the article conducted research aimed at determining the performance of the encryption algorithms Mars, AES (Rijndel), and Twofish, as well as their RSA add-ons. The dependence of the performance of the listed algorithms on the size and extension of the files encrypted using them, as well as the characteristics of the platform on which the encryption is performed, has been established. Recommendations have been made for the use of the studied algorithms in systems for monitoring the physical condition of personnel at critical informatization objects.
