Abstract

The encryption of digital images has become essential since it is vulnerable to interception while being transmitted or stored. A new image encryption algorithm to address the security challenges of traditional image encryption algorithms is presented in this research. The proposed scheme transforms the pixel information of an original image by taking into consideration the pixel location such that two neighboring pixels are processed via two separate algorithms. The proposed scheme utilized the Gray code number system. The experimental results and comparison shows the encrypted images were different from the original images. Also, pixel histogram revealed that the distribution of the plain images and their decrypted images have the same pixel histogram distributions, which means that there is a high correlation between the original images and decrypted images. The scheme also offers strong resistance to statistical attacks.
格雷码号码系统在图像安全中的性能分析
数字图像的加密变得至关重要,因为它在传输或存储时容易被拦截。本文提出了一种新的图像加密算法,以应对传统图像加密算法的安全挑战。所提出的方案通过考虑像素位置来变换原始图像的像素信息,使得通过两个单独的算法来处理两个相邻像素。该方案采用格雷码数字系统。实验结果和比较表明,加密后的图像与原始图像不同。此外,像素直方图揭示了普通图像及其解密图像的分布具有相同的像素直方图分布,这意味着原始图像和解密图像之间存在高相关性。该方案还提供了对统计攻击的强大抵抗力。
