Encryption is a process of converting an image from readable to unreadable form. Various Image encryption algorithm based on permutation and diffusion have been proposed However, most of the algorithm for the permutation process uses the chaos sequence to permute the image and considerably takes more time in shuffling the position of the image pixel. In this paper we proposed a new effective algorithm based on permutation-diffusion for image encryption to reduce the processing time of the encryption considerably. To make the encryption more stronger and confused, same image is fed to the diffusion process after permutation process. In the present work diffusion process is carried out with the traditional AES algorithm. Theoretical analyses and computer simulations both confirm that the new algorithm has high security and is very fast for practical image encryption.
