Permutation algorithme

WebAn image encryption based on simple permutation and diffusion operation using various 1D chaotic maps is proposed in this paper. The proposed technique first performs pixel permutation operation using various 1D chaotic maps and then performs pixel diffusion operation using pixel key generated by the Secure Hash Algorithm-256 and the plain image.
