%X The new image encryption algorithm was proposed based on multiple Fresnel diffraction transforms and phase encryption masks.The encrypted image was transformed into the random cipher-text matrix after multiple Fresnel diffraction transforms with phase encryption masks.The diffraction distances and phase encryption masks were the encryption keys mainly.The decrypted image was correct only when the all keys were correct.Numerical experiments show that the algorithm is robust to the attacks of the JPEG lossy compressing,cropping,strong superposing noise,resampling from the screen copy.Since the many keys cannot be decrypted,the algorithm has high security.
