摘要: 量子图像加密是量子图像处理中的典型问题。目前,国内外绝大多数的文献,都是基于某种几何变换,针对2n 2n尺寸的图像进行加密。这种加密方法不能满足任意大小尺寸的图像且加密具有周期性,即当变换次数达到某个数值时,加密图像就会得以恢复。基于像素颜色置乱,提出了一种新的加密方法。首先,采用改进的NEQR模型,表示彩色量子图像,然后对像素颜色进行置乱,通过改进的量子旋转门,把描述颜色的量子比特随机旋转,使原始图像不在包含自身信息,达到加密的效果。

Abstract: Quantum image encryption is a typical problem in quantum image processing. At present, most documents are based on geometric transformations, which is encrypt images of 2n 2n size. This encryption method cannot satisfy the image of any size and cyclicity, when the number of transformations reaches a certain number image will be restored. Encryption quantum color image based on pixel scrambling is proposed. Firstly, a color image is transformed into a quantum superposition state by improve NEQR model. Then each of the pixel color scrambling, by encryption rotation gates color random rotation. At this time, quantum color image not contain any original information to complete the encryption.
