In this paper, we propose a secure communication system composed of four chaotic oscillators. Two of those oscillators are unidirectionally coupled and employed as transmitter and receiver. The other two oscillators are indirectly coupled and are employed as keystream generators. The novelty lies in the generation of the same chaotic key both in the transmitter and receiver side for encryption and...
Method for secure information transmission based on generalized synchronization in the presence of noise is considered. Characteristics of chaotic systems used in transmitters and receivers are analyzed. Models of generators with delayed feedback, possessing all necessary requirements are revealed.
