Design and Analysis of a Novel Chaotic Image Encryption

A novel chaotic image encryption algorithm is proposed to overcome some drawbacks in the existed methods. The algorithm creates a relation between the plain image and the generated pesuedo-random numbers, which are consequently used in pixel position shuffled process and pixel value confusion process. Experimental results and analysis demonstrate that the algorithm has a large key space, it is very sensitive to keys, and it has a good ability of anti-information entropy attack, anti-statistics attacks and anti-differential attacks.
