In order to improve the effect of digital image encryption,after analyzing some image encryption algorithms,presents a digital image encryption algorithm—chaos encryption algorithm based on bit-plane of digital image.After dividing digital image's value into some bit-planes,the algorithm improves the traditional image encryption algorithm of image scrambling based on chaos by making use of Logistic chaotic sequences to scramble digital image's bit-plane.Experimental results show that the algorithm is feasible,universal and 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.
