A New Image Cipher Algorithm Based on Chaos

Article Preview

Abstract:

Cryptography is the field of information security technology research priorities. This paper proposes a chaos-based magic square image cipher algorithm. Firstly, it used magic square algorithm to transform the original image pre-processing, the process is the basis of the original magic square algorithm to improve the ranks of transform. Finally, using logistic, henon mappings generated by scrambling the array with the image, so that the image gray value and the location changed at the same time, encrypted final image. Through experimental validation, we prove that the algorithm has cipher effectiveness, and can effectively resist common attacks.
