Secure Chaotic Communication with Jerk Chaotic System Using Sliding Mode Control Method and Its Real Circuit Implementation

Chaotic systems (CS) are chosen for secure communication owing to their interesting features. So, various CS and effective synchronization methods are introduced. Sprott's jerk chaotic system (SJCS) is one of the simplest CS. It consists of only five terms with one nonlinearity. So, the usage of jerk CS in communication reduces the complexity of the system. In this work, sliding mode control (SMC)-based chaos synchronization of SJCS with analog circuit design is implemented for secure chaotic communication. The advantages of this secure chaotic communication application are to use a simple chaotic jerk system and achieve the synchronization with only one state SMC signal. Totally, a cost-effective secure chaotic communication system is obtained. There is no chaotic communication application realized by any jerk chaotic system. Moreover, the SMC method has not been used for the synchronization of a jerk CS. Furthermore, most of the chaotic communication studies are given only as numerical simulations. Unlike the others works, the design of circuit of the chaotic communication system is implemented and tested for real-world applications. In the implemented application, the information signal which is sent from the transmitter unit has been successfully obtained from the receiver unit
