A secure communication scheme using projective chaos synchronization. (English) Zbl 1060.93530

Chaos Solitons Fractals 22, No. 2, 477-481 (2004).
Summary: Most secure communication schemes using chaotic dynamics are based on identical synchronization. In this paper, we show the possibility of secure communication using projective synchronization (PS). The unpredictability of the scaling factor in projective synchronization can additionally enhance the security of communication. It is also showed that the scaling factor can be employed to improve the robustness against noise contamination. The feasibility of the communication scheme in high-dimensional chaotic systems, such as the hyperchaotic Rössler system, is demonstrated. Numerical results show the success in transmitting a sound signal through chaotic systems.
