“…In this regard, the observer-based chaotic synchronization problem [23] was investigated for a class of time-delay secure communication system. However, the proposed method is delay-independent and not applicable to the secure communication with fast time-varying delays, which means that the time derivative of time delay is unknown.…”

In this paper, a synchronization method of Lur'e systems for chaotic secure communication systems with interval time-varying delay feedback control is proposed. To increase communication security, the transmitted message is encrypted with the techniques of N -shift cipher and public key. Based on Lyapunov method and linear matrix inequality (LMI) formulation, new delay-dependent synchronization criteria are established to not only guarantee stable synchronization of both transmitter and receiver systems but also recover the transmitted original signal at the receiver. Throughout a numerical example, the validity and superiority of the proposed method are shown.

“…It is widely believed that there exist many benefits of having synchronization in many fields, such as secure communication, modelling brain activity and pattern recognition phenomena [1][2][3]. In particular, one of the interesting phenomena in complex networks is the synchronization, which is an important research subject with the rapidly increasing research, and there are a lot of results [4][5][6].…”

“…The systems can achieve synchronization if and only if the state error converges to 0. Till now, it is still the most widely used judgment of synchronization [3][4][5][6][7].…”

Abstract:In the practical applications, most of the chaotic systems are on the finite precision devices (such as computer), and their trajectories turn to be periodic which do not meet their evolution functions. The synchronization of digital chaotic systems has been studied in this paper. Both theoretical analysis and numerical experiments show that the digital systems can achieve synchronization. The relation between the roundoff of computer and synchronization has also been discussed in this paper.
