Justification of encryption algorithm for systems monitoring personnel condition of critical informatization objects

Abstract

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.
