A Novel Color Image Encryption Scheme Using Logistic Map and Quadratic Map Systems
In this work, we propose a color image encryption scheme based on logistic map and quadratic map systems. First, the color image is divided into three components (red (R), green (G), and blue (B)). The three components are mixed as single grayscale image, to permute the pixels positions; we have used two permutation index vectors for changing rows and columns position. Finally, the permuted grayscale image is encrypted. In order to evaluate the security of the proposed scheme, the entropy, key space analysis, key sensitivity analysis, the correlation of two adjacent pixels and differential attack were performed. The Experimental results and analyses show that the proposed scheme enable to reduce computing effort, to allow efficient and outperform many schemes given in the literature.
