  Abstract

In this paper, we propose the image encryption method which gradually uses NFSR(Non-linear Feedback Shift Register) and 2D CAT(Two-Dimensional Cellular Automata Transform). The encryption method is processed in the following order. First, NFSR is used to create a PN(pseudo noise) sequence, which matches the size of the original image. Then, the created sequence goes through a XOR operation with the original image and process the encipherment. Next, the gateway value is set to produce a 2D CAT basis function. The produced basis function is multiplied by encryption image that has been converted to process the 2D CAT encipherment. Lastly, the results of the experiment which are key space analysis, entropy analysis, and sensitivity analysis verify that the proposed method is efficient and very secure.
