Secure communication using a compound signal from generalized synchronizable chaotic systems. (English)
[J] Phys. Lett., A 241, No.6, 303-310 (1998). ISSN 0375-9601

Summary: By considering generalized synchronizable chaotic systems, the drive-auxiliary system variables are combined suitably using encryption key functions to obtain a compound chaotic signal. An appropriate feedback loop is constructed in the response-auxiliary system to achieve synchronization among the variables of the drive-auxiliary and response-auxiliary systems. We apply this approach to transmit analog and digital information signals in which the quality of the recovered signal is higher and the encoding is more secure.
