SECURE COMMUNICATION BY USING KEY FUNCTION BASED ON CHAOTIC SYSTEM SYNCHRONIZATION

摘要

In this Letter, a secure communication scheme based on the chaotic synchronization system is presented. By using key function, the secret signal is compound with complex chaotic signal in order to enhance the security of transmitted signal. Numerical simulation shows its feasibility. We apply this approach to transmit analog and digital signals in which the quality of retrieved signals is higher.
