Paper Abstract

Three-dimensional information encryption based on the phase extraction and phase shifting interferometry is proposed. The three-dimensional information with the pure amplitude and pure phase are constructed as the encryption target. First the complex amplitude of the three-dimensional information is calculated under the scalar diffraction theory, and its phase distribution is extracted independently. Then it is encrypted by the double random phase encoding, the complex amplitude is recorded by using two-step of phase shifting interferometry. Computer simulations demonstrate the feasibility, the robustness and the security of the proposed method. We analyze and simulate its resistance against the known plaintext attack as well. Furthermore, it is implied the potential of applying this method for the three-dimensional information encryption with much larger information quantity.
