The Sprott-B and Sprott-C are topologically equivalent but they have distinct structures. Chaos synchronization is realized between the two systems via linear coupling of systemic variable. Based on Lyapunov stability theory, the threshold value of coupling coefficients for synchronization of two systems is derived. The practical circuit is designed to realize chaos synchronization between the two systems and the experimental result verifies the conclusion. A new method for secure communication, which can increase the security of a communication system is proposed based on chaos synchronization between the above systems.
