Image encryption is studied to give an effective encryption method based on chaotic,fractal.Simulation and theory investigation is given.It is put forward that an image encryption method based on chaos,fractal and spiht.After DWT transformation for the original image,the high frequency and low frequency image are obtained.Corresponding to the low,the fractal encode is given.At the same time,corresponding to the high,spiht encode is provided.At last,chaotic encryption is given.The decode algorithm is on the opposite.Simulation testifies the correctness.Based on this,the hardware is realized based on DSP6000.
