传统的基于重影成像的加密(GIE)方案存在解密图像质量低、安全性不高的问题。在本文中,我们建议使用定制的数据容器和异或(XOR)操作来科普这些问题。该提案包括两个安全级别。第一级包括将主要信息变换成二进制信号(即,比特流)并将其与密钥比特流进行异或。在第二步中,第一级的结果被编码到一个精心设计的数据容器中,然后将其发送到GIE方案。该方法不仅具有很高的安全性,而且能够保证原始信息的无损恢复。一系列的数值结果证明了该方法的有效性和可行性。
The conventional ghost-imaging-based encryption (GIE) scheme has low-quality decrypted images and unsatisfied security. In this paper, we propose to cope with these issues using customized data container and exclusive-OR (XOR) operation. The proposal constitutes two security levels. The first level includes transforming the primary information into a binary signal (i.e., bit stream) under the ASCII standard and XORing it with the key bit stream. In the second step, the result in the first level is codified into an elaborate data container, which is then sent to the GIE scheme. The proposed approach not only possesses high security but ensures lossless recovery of the primary information as well. Its validity and feasibility have been supported by a series of numerical results.
