Synchronization of the chaotic secure communication system with output state delay

Robust finite-time chaos synchronization of time-delay chaotic systems and its application in secure communication

“…Figure 6 shows that the original message can be completely recovered at the reception end when delay τ = 1 6 . In Changchien et al (2009), the authors tried to recover the signal with different time delays. They found that when the time-delay exceeded 0.31 s the synchronization between the transmission and reception ends cannot be achieved and the original message cannot be recovered.…”

“…Some researchers have studied secure communication based on the determined time-delay chaotic system (Changchien et al, 2009). But it is seldom to see the secure communication scheme based on the time-delay chaotic systems with uncertainties.…”
