Abstract

In this paper, we proposed a modified chaotic based image encryption scheme using two logistic maps and two-dimensional baker map. In encryption process pixel, integration of diffusion and chaotic confusion are adopted. For pixel diffusion, we employed two-dimensional baker map to shuffle the positions of image pixels which can diffuse the relationship between the cipher-image and plain-image. Further, XOR operation is used with logistic map to generate a cipher image. To make the cipher more robust against any attack, the secret key is modified after encryption until the image is exhausted. Experimental results of the chaos-based encryption are carried out with detailed analysis and their security is discussed.
