摘　　要：针对量子索引图像在量子计算机信息安全领域中的应用问题,本文提出一种基于分量和(sum of components,SoC)的量子索引图像信息隐藏算法。量子索引图像包括数据矩阵和调色板2种数据结构。基于SoC的量子索引图像信息隐藏算法首先根据颜色值分量和的奇偶性(1或0)和颜色值距离,为量子调色板中每一个颜色匹配一个符合条件的颜色组成颜色对;嵌入消息时,根据颜色对和消息比特对量子数据矩阵的像素索引值进行更新;提取消息时,量子索引图像每个像素颜色值分量和的奇偶性即为嵌入的消息,属于盲提取算法。此方法可在未来量子计算机上执行。根据经典计算机上的仿真结果从视觉质量、嵌入容量、鲁棒性和安全性4个方面验证了该方法的有效性。Aiming at the application of quantum indexed images in the field of information security on quantum computers,a quantum indexed image information hiding algorithm based on the sum of components(SoC)is proposed in the paper.A quantum indexed image contains 2 data structures:quantum data matrix and quantum palette.In the quantum indexed image SoC information hiding algorithm,first according to the parity of the color value component sum(1 or 0)and distance of the color values,match each color in the quantum palette with a qualified color to form a color pair;When the message is embedded,the pixel index value in the quantum data matrix is updated according to the color pair and the message bit;When the message is extracted,the parity of each pixel color value component sum in the quantum indexed image is the message bit,and this is a blind extraction algorithm.This method can be performed on future quantum computers.According to the simulation results on a classical computer,the validness of this method is verified from 4 aspects:visual quality,embedding capacity,robustness and security.
