Description
Summary:This paper is focused on design of an image encryption algorithm, analysis of its properties and verification of achieved results. The algorithm is based on variant of chaotic logistic map, which shifts locations and intensities of image pixels. This approach also establishes dependencies between image pixels. All operations which are performed allow usage of grayscale images with arbitrary resolution. Paper also discusses size of keyspace and key sensitivity of proposed approach. Verification of results is done on set of four images and five keys by means of statistical and differential attacks.
