A digital image encryption algorithm,dual scrambling based on chaos of pixel position and pixel value,is presented.The algorithm uses Logistic chaotic sequences to scramble digital image pixel positions and then scramble digital image pixel values by using Logistic chaotic sequences again.Consequently,dual scrambling of pixel position and value based on chaos is completed and the algorithm improves the traditional image encryption algorithm of image scrambling based on chaos.Experimental results show that the effect of the proposed method is perfect and it outperforms the traditional image encryption algorithm based on Logistic chaos sequences in digital image pixel dots.
