摘要：

In this paper, we propose an image encryption algorithm that is based on GF(2(8)) transformations, using the Arnold cat map and incorporating the nonlinear chaotic algorithm. The plain image is processed with the nonlinear chaotic algorithm and is shuffled iteratively with the Arnold cat map, while transforming the image pixel values into GF(2(8)). We show that the encryption characteristics of this approach are better as compared to some well known encryption algorithms.
