Abstract:
In order to increase the security and robustness of quantum images, this study combined the quantum DNA codec with quantum Hilbert scrambling to offer an enhanced quantum image encryption technique. Initially, to accomplish pixel-level diffusion and create enough key space for the picture, a quantum DNA codec was created to encode and decode the pixel color information of the quantum image using its special biological properties. Second, we used quantum Hilbert scrambling to muddle the image position data in order to double the encryption effect. In order to enhance the encryption effect, the altered picture was then employed as a key matrix in a quantum XOR operation with the original image. The inverse transformation of the encryption procedure may be used to decrypt the picture since all the quantum operations employed in this research are reversible. The two-dimensional optical image encryption technique presented in this study may significantly strengthen the anti-attack of quantum picture, according to experimental simulation and result analysis. The correlation chart demonstrates that the average information entropy of the RGB three channels is more than 7.999, the average NPCR and UACI are respectively 99.61% and 33.42%, and the peak value of the ciphertext picture histogram is uniform. It offers more security and robustness than earlier algorithms and can withstand statistical analysis and differential assaults.
摘要:
为了提高量子图像的安全性和鲁棒性,本研究将量子DNA编解码器与量子希尔伯特置乱相结合,提供了一种增强的量子图像加密技术。最初,为了实现像素级扩散并为图片创建足够的关键空间,创建了量子DNA编解码器,以使用其特殊的生物学特性对量子图像的像素颜色信息进行编码和解码。第二,我们使用量子希尔伯特置乱来混淆图像位置数据,以使加密效果加倍。为了增强加密效果,然后,将更改后的图片用作与原始图像进行量子XOR操作的关键矩阵。加密过程的逆变换可用于解密图片,因为本研究中采用的所有量子运算都是可逆的。本研究提出的二维光学图像加密技术可以显著加强量子图像的抗攻击,根据实验仿真和结果分析。相关图表明,RGB三个通道的平均信息熵大于7.999,平均NPCR和UACI分别为99.61%和33.42%,密文图片直方图的峰值是均匀的。它比早期的算法提供了更多的安全性和鲁棒性,可以承受统计分析和差分攻击。
