Improvement and Implementation of 3D Color Image Encryption

Encryption processing color images in 3D space on the computational complexity and space requirements for the larger, less efficient encryption problem, the color image is converted to three dimensions on a two-dimensional gray-scale image processing, thereby speeding up the encryption speed. In order to improve the robustness of the algorithm, the chaotic sequence turns to a homogeneous distribution of the sequence, to achieve more desirable characteristics of a pseudo-random. Logistic map and Chebyshev map for poor single chaotic encryption algorithm security problems, the combination of higher complexity of the dual chaotic system. Realization of the pixels confusion and diffusion effective with the chaotic sequence which generated by the dual chaotic system,the method of image encryption is improved.
