Nowadays, images are widely used in real-time to share vital information that can be easily attacked. Therefore, the security of image data is of prime concern. In this work, we provide hardware solutions for preserving image data. Here, the lightweight block cipher GIFT was used for the integrated encryption and decryption operation on an FPGA device. The design is capable of processing standard gray-level and RGB color image sizes of \(256 \times 256\), \(512 \times 512\), and \(1024 \times 1024\). Our design was implemented on Xilinx Zynq Ultrascale+ xczu9eg FPGA device available on ZCU102 SoC platform. It took 103 slices, worked up to 590 MHz of frequency and consumed 673 mW power. Statistical metrics such as histogram, key sensitivity, correlation, entropy, NPCR, UACI, PSNR, MSE, and SSIM were computed. Correlation coefficients, NPCR, UACI, and entropy values were compared to the existing solutions. The decreases in average correlation coefficient in horizontal, vertical, and diagonal directions were 99.59%, 99.97%, and 99.92%.

如今，图像被广泛用于实时共享容易受到攻击的重要信息。因此，图像数据的安全性是首要关注的问题。在这项工作中，我们提供了用于保存图像数据的硬件解决方案。在这里，轻量级分组密码 GIFT 用于 FPGA 设备上的集成加密和解密操作。该设计能够处理\(256 \times 256\)、\(512 \times 512\)和\(1024 \times 1024\)的标准灰度和RGB彩色图像尺寸. 我们的设计是在 ZCU102 SoC 平台上可用的 Xilinx Zynq Ultrascale+ xczu9eg FPGA 器件上实现的。它需要 103 个切片，工作频率高达 590 MHz，消耗 673 mW 功率。计算了统计指标，例如直方图、密钥灵敏度、相关性、熵、NPCR、UACI、PSNR、MSE 和 SSIM。将相关系数、NPCR、UACI 和熵值与现有解决方案进行了比较。水平、垂直和对角线方向的平均相关系数下降幅度分别为99.59%、99.97%和99.92%。
