Abstract


Synchronous control of chaotic systems has been chaotic frontier topics in the field , is also a hot topic of nonlinear science . Chaos synchronization theory applied to secure communication has become a new research direction of communication theory . Has attractive prospect this article work mainly around the chaotic synchronization and its application in confidential communications research and discussion . chapter describes chaotic development history , status and significance and the main contents of this article . Chapter II of this article used relevant theoretical knowledge . proposed the idea to use the contraction theoretical study of nonlinear systems synchronization problem , to prove the complete synchronization between Chen system and achieve coupled by tectonic contraction virtual systems , as well as to achieve coexistence between the system part of the variable anti- synchronization and synchronization. remaining variables Chapter IV , Chapter realization coupled Chen system fully synchronized based on combined chaotic masking technology design communication programs for secure communication , and synchronization status and encrypted signals interactions between relationship Chapter V , with the current hotspot hyperchaotic combined with chaotic modulation technology design communication programs , the use of parameter identification , analysis , and proposed to useful information drop limit frequency modulation again after the transmitter system parameters as well as the need to eliminate the noise component of the transmitter system state to improve the quality of chaotic communication .
