New S-Box Transformation Based on Chaotic System for Image Encryption

摘要

Chaos theory one of the complex approaches with encryption methods is known as a perfect candidate. This is due to using cryptography applications to its properties like unpredictability and sensitive initial states. S-box based on Logistics Map has been suggested. in this paper establish a new method of composition, saving time in encryption, allowing a high-efficiency non-linearity of random sequences of the created values. showed a new diffusion system and suggested utilizing the dispersion principle, based on the Lorenz Map, disengage the color points. (R, G, B). Initiate this proposal by shuffling all pixels in tow steps for each color channel to swap the pixels horizontally, vertically, or diagonally, last step marked with an XOR. The image encryption method reasonably requires a few milliseconds, and the considerable period for the familiar image to be decrypted fairly close as the images. block encoder is reversible to the developed algorithm. The unique experiments merely demonstrate that the information security capabilities will be both safe more efficient, the current S-Box analysis with statistical criteria, including balanced criteria (BC), completeness criteria (CC), avalanche criteria (AC), strict avalanche criteria (SAC), and invertibility, the analysis of performance tests demonstrate the strong cryptographic properties of the S-box discussed in this new S-Box. The consistent result of our critical analysis of picture quality evaluation, differential attacks (NPSR), (UACI), entropy information, and pixels correlation show the peculiar quality and political strength of encryption processing.
