A New Image Encryption Scheme Using an Enhanced Logistic Map

In this paper, we propose new chaotic version to enhance Logistic Map (ELM), this latter owns the large chaotic ambit and the best chaotic performances compared to classical logistic map. We have carried out investigations on its applications, by proposing a chaotic magic transform (CMT), an efficient permutation in the pixel locations of the image and their values with low time in encryption and decryption process. In addition, a new image encryption scheme has been proposed. Security analysis and simulation results have been performed, this proved that the proposed scheme is capable to safeguard images at low duration and a high safety level and also able to resist into several known attacks.
