“…These encrypted ID, PW, and OTP are then decrypted by the server and used to verify the client. For the proposed OTP authentication, we use a two-step quadrature phase-shifting holographic optical setup that employs simply two polarizers and one phase retarder to produce the quadrature phase shifting [21]. Figure 2 is the optical schematic for the proposed OTP authentication using two-step phase-shifting digital holographic optical encryption.…”

A new optical one-time password (OTP) authentication method using digital holography is proposed, which enhances security strength in the authentication system. A challenge-response optical OTP algorithm based on two-factor authentication is presented using two-step phase-shifting digital holography, and two-way authentication is also performed using challenge-response handshake in both directions. Identification (ID), password (PW), and OTP are encrypted with a shared key by applying phase-shifting digital holography, and these encrypted pieces of information are verified by each party by means of the shared key. The encrypted digital holograms are obtained by Fourier-transform holography and are recorded on a CCD with 256 quantized gray-level intensities. Because the intensity pattern of such an encrypted digital hologram is distributed randomly, it guards against a replay attack and results in higher security level. The proposed method has advantages, in that it does not require a time-synchronized OTP, and can be applied to various authentication applications. Computer experiments show that the proposed method is feasible for high-security OTP authentication.

“…In traditional testing, the dominating systematic error is the reference surface with 3~5 nm rms. In absolute rotation testing, the reference surface is canceled out, and the systematic errors include errors introduced by the rotation stage, interferometric optics error, phase-shifting error [12], environment noise and so on. The rotation stage's error can be controlled within 0.2° angle error and 0.2 pixel decentration error.…”

Based on Zernike polynomial fitting, we propose an algorithm believed to be new for interferometric measurements of rotationally asymmetric surface deviation of optics. This method tests and calculates each angular surface by choosing specified rotation angles with lowest error. The entire figure can be obtained by superimposing these sub-surfaces. Simulation and experiment studies for verifying the proposed algorithm are presented. The results show that the accuracy of the proposed method is higher than single-rotation algorithm and almost comparable to the rotation-averaging algorithm with fewer rotation measurements. The new algorithm can achieve a balance between the efficiency and accuracy.

“…One approach among them is a method to use an optical holography [9,10], but this technique makes it difficult to store and transmit the encrypted information over a digital network owing to complex function with phase and amplitude. Recently, methods using a phase-shifting digital holographic technique have been presented [10][11][12], which can easily performs optical encryption and decryption to record and reconstruct the complex values, and especially some papers on the optical encryption using the phase-shifting digital holography were reported by us [13][14][15][16][17][18]. In this paper, we propose a new security enhanced optical OTP authentication method with 2-step quadrature phaseshifting digital holography using orthogonal polarization, and show the performance of the proposed system for the OTP authentication.…”

We propose a new optical one-time password(OTP) authentication method by using digital holography, which enhances security strength in the cryptosystem compared to the conventional electronic OTP method. In this paper, a challengeresponse optical OTP authentication based on two-factor authentication is presented by 2-step quadrature phase-shifting digital holography using orthogonal polarization, and two-way authentication is also performed using the challengeresponse handshake in both directions. The ID(identification), PW(password) and OTP information are encrypted with a shared key by applying phase-shifting digital holography, and these encrypted information are verified each other by the shared key. Because the encrypted digital holograms which are transmitted to the other party are expressed as random distribution, it guards against a replay attack and results in higher security level. Optically, encrypted digital hologram in our method is Fourier transform hologram and is recorded on CCD with 256 gray-level quantized intensities. The proposed method has an advantage that it does not need a time-synchronized OTP and can be applied to various security services. Computer experiments show that the proposed method is suitable for high secure OTP authentication.
