To efficiently protect digital images, this paper proposes a novel image encryption scheme using the concepts of Josephus permutation and image filtering. It adopts the well-known architecture of confusion and diffusion. The Josephus permutation is designed to achieve the confusion property by fast separating adjacent pixels into different rows and columns, while the image filtering is to obtain the diffusion property by spreading tiny change in plain-image to the whole cipher-image. Simulation results demonstrate that the proposed image encryption scheme can encrypt different kinds of images into noise-like cipher-images. Security analysis shows that it has high security level and can outperform several other image encryption schemes.
