A note on chaotic secure communication systems

Research output: Contribution to journalArticle

Abstract

This paper presents a new way to transmit and retrieve an information-bearing signal via chaotic systems. In contrast to existing schemes with one transmission line, a two-channel transmission method is adopted for the purpose of faster synchronization and higher security. Basically, an output of the chaotic transmitter is sent for synchronization-only, with no connection to the information signal. The other channel transmits a signal generated from a highly nonlinear function of the chaotic states and the information-bearing signal. While the first channel serves the purpose of efficient synchronization, the second channel is used for complicated encryption and, therefore, improved security/privacy. Simulation results validate the new chaos-based secure communication method.
