An Encryption Algorithm by Scrambling Image with Sudoku Grids Matrix

Abstract:

An image encryption algorithm by scrambling both the pixel location and the pixel value with sudoku grids matrix is proposed in this paper. As there is a certain mapping mode Between the Natural order and the numeric order in the row, line and block in sudoku grids, the proposed algorithm adopts the sudoku grids as secret key and scrambles the image according to the certain mapping mode. The algorithm is suitable for image with any size. The simulation experiments show that it has good encryption efficiency and perfect encryption effects. Also the transferring attack can be distributed equally by the algorithm which has high robustness, and good restoration result is produced.
