摘要：
The development of computer networks makes image files transportation via network become more and more convenient. However, the security of most existing image encryption methods requires to be further improved. In this paper, we present an Image Encryption algorithm combining an Improved generalized discrete Arnold transformation and a Nonlinear Chaotic map (IEIANC). It adopts the scrambling and diffusion encryption framework. First, it designs an extra 256-bit key to make the key space large enough. Next, it utilizes an improved generalized discrete Arnold transformation to scramble image pixels, and divides the scrambled image into several blocks. Finally, it applies a nonlinear chaotic map to diffuse these blocks. The experimental results show the effectiveness of the proposed algorithm. © 2016 ICIC International.
