Chua's design based on hysteresis comparator and its application to image encryption

In order to improve the chaotic dynamics behavior of Chua’s circuit, simplify the circuit design, using hysteresis comparator to design a new class of Chua’s circuit, according to the equation of each state variable corresponding relation connect each module circuit for its physical circuit, theoretical analysis and simulation results are consistent, which prove the accuracy of circuit and the design is effective. chaotic sequence to encrypt image, the encryption histogram, results show that the new systems are very sensitive to image key and plaintext, key space is large, chaotic system applied to image encryption has higher safety performance.
