Abstract：In order to enhance the effective protection of color images, the multi-steady characteristics of a four-dimensional magnetron memristive model is analyzed by Lyapunov exponent spectrum and bifurcation diagrams. The color image encryption based on this system is implemented using Python programming. The analysis of the pixel histogram, the correlation between adjacent pixels, the anti-attack capability and the key sensitivity shows that the encryption performance of the chaotic state of the memristive system is superior to its periodic state. The analysis of the characteristic provides a method and support for selecting the appropriate key.
