本文提出了一种基于定制数据容器的信息加密方案，该方案可以从计算重影成像加密的密文中完全恢复原始信息。该方案从两个方面解决了计算鬼像固有的线性和机理所带来的严重问题。首先，要加密的主要信息被转换成信息位，其用于控制定制数据容器的形成。然后，利用随机生成的数据容器对其进行异或（XOR）运算，并根据Logistic映射产生的随机序列对XOR编码结果进行置乱，从而破坏了密码系统的线性。其次，代替使用随机的仅相位掩模，使用从所设计的Hadamard矩阵的行导出的2D图案检索的多个相位掩模来记录测量的强度。这些相位掩模之间的冗余度很低，这可以大大减少所需的纯相位掩模的数量。同时，将Logistic映射的条件作为密钥，由于其对微小变化的高度敏感性，可以大大提高安全级别。数值仿真结果表明了该方法的有效性和可行性。(C)根据OSA开放获取出版协议的条款，2019年美国光学学会
In this paper, a novel information encryption scheme has been proposed based on the customized data container, where the primary information can be recovered completely from the ciphertext encrypted with computational ghost imaging. From two aspects, the proposed scheme solves the serious issues caused by the inherent linearity and mechanism of computational ghost imaging. First, the primary information to be encrypted is transformed into the bits of information, which is used to control the formation of the customized data container. Then, the exclusive-OR (XOR) operation is performed on it with a randomly generated data container, and the XOR encoding result is scrambled based on the random sequence engendered with the logistic map so that the linearity of the cryptosystem is destroyed. Second, instead of using random phase-only masks, a number of phase masks retrieved from 2D patterns derived from the rows of the designed Hadamard matrix are used to record the measured intensities. The redundancy between these phase masks is low, which can reduce the number of the required phase-only masks greatly. Meanwhile, the conditions of the logistic map are considered as the secret keys, which can enhance the security level greatly due to their high sensitivity to tiny variation. The validity and feasibility of the proposed method have been demonstrated with a set of numerical simulations.
