Abstract

In this paper, we study the design and implementation of digital secure communication systems via synchronized Sprott chaotic circuits. First, using the variable structure control (VSC) technique, we propose a control law to cope with the synchronization problem of the master and slave Sprott circuits. Then, according to the concept of equivalence control, it can ensure that the message embedded in the transmitter (master Sprott circuit) can be recovered in the receiver (slave Sprott circuit). Then a digital secure communication system based on synchronized coupled chaotic systems is implemented using basic electronic components. Finally, both simulation results and the experimental results demonstrate the proposed VSC-based synchronization scheme's success in the secure communication application.
