Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Cryptographic System Based on the Chaotic Lorenz System S.V. DANILKIN, P.I. KARASEV, M.A. RUSANOV, AHMED ADNAN LATEEF The article deals with the problem of using chaotic systems as a basis for designing new cryptosystems. A comparison of classical cryptography systems and physical chaotic systems is carried out, and also a new encryption algorithm written in the njs programming language is presented based on the system of Lorenz differential equations, and also indicates the possibility of using it when implementing the Nginx module for encrypting transmitted data. Keywords: Cryptographic systems, chaotic systems, system of Lorenz differential equations, Nginx, Nginx modules, njs. DOI: 10.25791/pribor.3.2023.1398 Pp. 48-53.
