Open publisher page 1 citations

Abstract

A new digital image scrambling algorithm based on chaotic system is presented in this paper for image encryption.The chaotic sequence generated by Logistic-ma Pis discretized to generate the matrixes which control the rules of exchange and the displacement distance both in horizontal and vertical direction.By traversing each pixel in image,each pixel is exchanged with another pixel in the image following the rules.Simulation experimental result shows that this algorithm has good scrambling performance,high efficiency and security.
