| Abstract: | A new image encryption algorithm based on Arnold transform is proposed by exploiting the pseudorandomness and the initial sensitivity of 2D discrete chaotic maps. The proposed schema changes the position and pixel value of the image. The experimental results indicate the efficiency of the algorithm. |
