Improved Encryption Algorithm of Images Based on Three-Dimensional Chaos

It describes an improved encryption algorithm of a three-dimensional image based on multiple chaotic systems. The algorithm uses a variety of chaotic encryption system to cut the image into three-dimensional matrix systems, in three-dimensional space do the image scrambling transformation, three-dimensional chaotic sequence output by multiple chaotic systems achieved three color pixel substitution transformation of the spatial color image. Finally, according to the theoretical analysis and simulation results it shows that the encryption algorithm with large key space, good confidentiality, and the pixel values of the encryption image has a random uniform distribution features and zero correlation of the neighboring pixel values, verifies the proposed scheme has high security.
