Chaos Synchronizations in Chua's Circuits with 5-scolls

Chaos is a kind of complicated and random phenomenon that is determined wholly by deterministic nonlinear systems and have high sensitivity to original conditions.Chaotic secure communication have the advantages of high security and easiness of realization,etc.Chaos synchronization is the basic condition to realize the Chaotic secure communication system.Studying the synchronizations of chaotic system with n-scolls can highly improve the system's sensitivity and more difficult to decrypt.Applying coupling synchronization and adaptive synchronization to chua's chaotic circuits with 5-scolls,designing the right synchronized functions and choosing the correct parameters,both chaotic systems can reach the synchronization.Comparing with the synchronized performance,some conclusions can be draw:adaptive synchronization have less time to reach synchronization,but couple synchronization have less bias error.To design the chaotic secure communication,the right synchronization should be chosen according to the specific conditions.
