Full text: PDF


By analyzing and researching several digital chaotic image encryption algorithms, this paper designs a symmetric image encryption scheme based on the three-dimensional Henon chaotic map and the general Cat chaotic map. In this scheme, the chaotic sequence of general Cat map is used as the initialization sequence to confuse the positions of image pixels; the three-dimensional Henon chaotic map can diffuse the image pixels; Then, repeat the confusing and diffusing process to increase the resistance to statistical and related attacks. Thorough experimental tests are carried out with detailed analysis, demonstrating the high security and fast encryption speed of the new scheme.
