Performance Improvement for Image Cipher Algorithm Based on Chaos

Abstract:

The authors improve the performance of an image cipher algorithm based chaos theory. The authors do Preprocessing for the algorithm firstly, makes spatial scrambling based on image blocking in order to interrupt pixel position, then furthering this interruption through Arnold mapping, and transforms pixel RGB color space through optimized Arnold Mapping. At last, we get the final encrypted image through a series of iteration. With some theoretical analysis of security, this algorithm has a lot of advantages such as, good diffusion properties, its key space is safe enough to resist exhaustive-key-research attack, high effectiveness and resisting common attack successfully, but it needs improvements on some aspects, such as the key sensitivity.
