Secure Communication using Compound Signal from Generalized Synchronizable Chaotic Systems

摘要

By considering generalized synchronizable chaotic systems, thedrive-auxiliary system variables are combined suitably using encryption keyfunctions to obtain a compound chaotic signal. An appropriate feedback loop isconstructed in the response-auxiliary system to achieve synchronization amongthe variables of the drive-auxiliary and response-auxiliary systems. We applythis approach to transmit analog and digital information signals in which thequality of the recovered signal is higher and the encoding is more secure.
