Abstract
According to the existing problems like that the algorithm is very complex, the quantity of operation is large and safety is not advanced in the present digital image encryption, this study has put forward a new chaotic system based on Logistic generation and transformation to realize the sequence image encryption, the algorithm gave the traditional chaotic series a new purpose. It used two kinds of ways on the comprehensive encryption for the same image that is respectively from the alternative operating on image pixel grayscale value and the confusion of the pixel position in the specific operation method. The experiment results show that the algorithm has good encryption effect and can withstand statistical analysis and attack operation, the amount of the key is large with high safety, in line with the requirements of modern technology to image encryption.
