| Abstract: | On the basis of chaos theory,a gray-scale image encryption algorithm is presented.It generates XOR matrixes and re- placement matrixes by using the Logistic Mapping,then divides the gray-scale image into pieces and encrypts them in turn.Ex- perimental simulation shows that the encryption algorithm has a good effect of encryption. |

| Keywords: | Logistic chaotic sequence XOR matrix replacement matrix image encryption |
