Application of hyper-chaotic Lorenz system for data transmission

Abstract

Abstract A novel method of digital data transmission is developed and experimentally investigated. The main idea of the method is to convert digital data into a chaotic spectrum, mix it with a background signal and transmit to receiver using TCP/IP protocol. The hyper-chaotic Lorenz system of differential equations is used as a source for carriers of the chaotic spectrum. Chaotic synchronization is not used in the method, that allows to improve stability of data transmission. Human voice is used as the background signal. Therefore, the method allows one to use single communication channel for transmission of different signals without losses. Numerical investigations approved that the chaotic signal transformation does not change chaotic nature of the Lorenz system. Thus, developed method demonstrates high privacy level.
