A color information encryption method in gyrator transform domain that based on an asymmetric cryptosystem is proposed. In encryption process, a color image is first decomposed into red, blue and green color channels. Each of these channels are independently attached to the first random phase mask (RPM) placed at the image plane and then gyrator transformed. The transformed image is phase-truncated to get encoded image and amplitude-truncated to produce first decryption phase key. The encoded image is attached to the second random phase mask placed at the frequency plane and then again gyrator transformed. The resulted image is phase-truncated to get final encoded image and amplitude-truncated to generate second decryption phase key. The decryption phase keys provide asymmetric keys whereas the transformation angles of gyrator transform offer extra keys. Compared to previous asymmetric cryptosystem, the proposed system provides parametric precision of optical configuration and offers a high level robustness against existing attacks. Simulation results are presented to support the feasibility of the proposed method.
