傅里叶光学光学加密衍射成像相位恢复算法 Fourier optics optical encryption diffraction imaging phase retrieval algorithm

摘要

为了简化加密系统光学结构以及提高安全性，本文利用相位板抽取方法提出了一种基于衍射成像模型的光学加密方法。该方法在光路中放置三个随机相位板，在输出平面上利用CCD 记录衍射光强分布作为密文。在加密时，每次均抽取出其中一个随机相位板，由另外两个随机相位板进行光学加密，一共记录三幅衍射光强分布。解密过程采用数字方法，利用相位恢复迭代算法即可由密文和密钥恢复原始图像。该光学加密方法在加密过程中不需要移动光学器件，只需记录光强分布作为密文，因而便于光学实现。仿真实验表明该光学加密方法可以实现灰度图像的加密，具有多重加密密钥，安全性较高。同时，该加密方法具有一定的抗噪声和剪切攻击的能力，因而该方法可以用于传输环境比较恶劣的条件下。

Abstract

In order to simplify the optical structure of the encryption system and enhance the security, an encryption method based on diffraction imaging principle is proposed by using phase mask removal method. In the proposed optical encryption approach, three random phase masks are placed in the optical path, and a CCD camera in the output plane is used to record the diffraction intensity distribution as ciphertext. In encryption, one of the three random phase masks is removed at a time, and the other two masks are used for optical encryption. Accordingly, three diffraction intensity distributions are recorded in all. Decryption process uses digital method. The original image can be retrieved from the ciphertext and security keys by means of phase retrieval algorithm. The encryption could be achieved without any movement of the optical devices, and only intensity distributions are recorded as ciphertext, thereby facilitating the optical implementation. Simulation results show that the proposal can achieve gray image encryption, and have multiple encryption keys. As a result, high security is gained. Meanwhile, the proposed approach has the ability to resist noise attack and occlusion attack, which makes the proposal suitable for harsh transmission conditions.
