Abstract

For purpose of meeting the requirement of encryption security, this paper brings an image encryption scheme based on chaotic system, block scrambling, swapping of rows and columns. The chaotic matrixes and index sequences are obtained to realize the rows and columns exchange and block scrambling, and the diffusion method is used to make the pixels fully diffuse so that the security can be improve. The image gray distribution, the correlation, the key space and the robustness against cropping attack are analyzed and simulated. The results show that the proposed scheme has high security and provides theoretical guidance.
