High Speed Color Image Encryption Using Pixel Shuffling With 1-D MLCA

Due to the development of the Internet and the communication network environment, image transmissions occur very frequently. In such an environment, the color image is likely to be distorted by noise. Image shuffling is a technique which resists distortion and deletion attacks. In this paper, we propose a speed-up method for shuffling pixels in the color image encryption system. In that step of shuffling, we use 1-D MLCAs to shuffle the pixel position of an image. In fact 1-D MLCA is higher in randomness than the conventional chaotic map and faster than the 3-D generalized chaotic cat map. The comparison of the execution time between the proposed method and the existing method is made.
