Image Encryption Algorithm Based on Coupled Toggle Cellular Automata
基于耦合触发细胞自动机的图像加密算法

A novel image encryption algorithm,which is based on one dimension cellular automata(1-D CA),was proposed.Before encryption,unlike other algorithms,a simple pretreatment was adopted to conceal visual information of original image,which was separated into two parts according to its information characteristic.These two parts were encrypted parallelly.Since secret key was divided into two subkeys corresponding to two subsections of image,only obtaining two parts of cipher text could receive decrypt correctly.T...
