Abstract
According to the existing problems like the algorithm is very complex,the quantity of operation is large and safety is not advanced in the present digital image encryption,a digital image encryption algorithm based on the chaotic sequence transform is proposed.The algorithm encrypt the image from two aspects that the pixel grayscale value and pixel position through two different chaotic sequence transform of the Logistic and Hybrid.The experiments 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.
