Abstract: We propose a new encryption strategy based on the Lorenz chaotic system. Scrambling and diffusion techniques are carried out availing the chaotic sequences rendered by Lorenz system. The chaotic sequences tactically clutter the pixel positions and curtail the relationship between the original image and the encrypted image.Wittingly a high-dimensional system delivers a well robust cryptosystem bearing good efficiency and resistivity. Here we demonstrate through dilated measures and statistical analyses that the proposed system prominently improves security scales and is also potential in withstanding to various sort of attacks. Securing images in cyber space became vital in communication for instance, military affairs, national security, diplomatic affairs, medical database and so on expanding its attention broadly.
