摘要：
The paper tries to give a new scheme for image encryption, which innovatively introduced the idea of Langton’s Ant cellular automaton to scramble the image. We virtualize a chessboard with the size of the image, and let the ant crawls on it by following the rules which Langton gives and steps generated by intertwining logistic map, then to determine the position of the plain image’s pixels in the scrambling image according to the position which the ant stay each time. Lastly, the PWLCM chaos map has been used to diffuse the image. Experimental results and security analysis show that our scheme is secure and can be used in image encryption and transmission.
