摘　　要：图像加密是保证数字图像在互联网上进行安全传输的关键环节。文中提出了一种基于交替量子随机行走(AQW)与异或操作的彩色量子图像加密算法。首先,对原始彩色图像进行彩色量子图像表示法(NCQI)表示,构建量子线路,利用受控AQW生成的二进制概率矩阵构建量子异或矩阵,完成对原始量子图像的加密操作,解密过程是加密过程的逆过程。AQW的初始条件是保证量子图像加密算法安全性的关键。通过对提出的加密模型进行经典计算机上的仿真实验,验证了该量子图像加密模型的安全性。Image encryption is a key link to ensure the secure transmission of digital images over the Internet.In this paper,a color quantum image encryption algorithm based on alternating quantum random walk(AQW)and XOR operation is proposed.Firstly,the original color image is represented by color quantum image representation(NCQI),the quantum circuit is constructed,and the quantum XOR matrix is constructed by using the binary probability matrix generated by the controlled AQW to complete the encryption operation of the original quantum image,and the decryption process is the reverse process of the encryption process.The initial condition of AQW is the key to guaranteeing the security of quantum image encryption algorithms.The security of the proposed quantum image encryption model is verified through the simulation experiment of on classical computer.
