In the optical implementation of image encryption using random phase encoding proposed by Re´ fre´ gier and Javidi the random phase mask is not band limited. Speckle noise can thus destroy optical reconstruction of the encrypted images. We demonstrate encryption of speckle-free kinoforms by smoothed random phase masks. Optical verification of the encrypted images is shown.
