In this paper, we present a new image encryption approach by generating the key streams using the fractional-order logistics map, which is due to the advantages it offers such as better chaotic range and more parameters. The algorithm depend on the permutation and diffusion processes, in which pixels are shifted with two step numbers and we also use two-vector index to change the locations of columns and rows.To prove the algorithm’s effectiveness in image encryption, it was submitted to a series of analyses and testing, including entropy, histogram, key sensitivity, and other tests.. The simulation results proved that our encryption system has excellent encryption results, in addition to a high security performance compared to various literature.
