Memristive Chaotic Circuit Designed for Image Encryption

Memristor is a device with nonlinear and memory characteristics, and it is an appropriate candidate for constructing chaotic and hyperchaotic systems. In this work, we have designed a memristor model and subsequently built a memristor chaotic circuit. The basic dynamic behavior of the system with varying the circuit parameters was studied in detail by using the traditional nonlinear analysis method. In addition, the memristive chaotic system also has the advantages of being extremely sensitive to system parameters, initial conditions and unpredictability, aperiodicity and structural complexity. The successful application of such design on image encryption and decryption with high security was eventually demonstrated.
