发布时间:2018-08-20 07:34
【摘要】:计算机的电磁辐射会包含视频信息从而造成的信息泄漏,本文在随机置乱的基础上,根据人眼视觉效应提出了互补置乱的方法来抑制视频信息通过电磁辐射的泄漏.通过对相邻的每帧视频信息进行加减随机噪声,使得人眼视觉观察效果抵消掉噪声对视频图像的干扰,在叠加噪声的同时,保证了视频图像的清晰度,同样也达到了抑制视频信息电磁泄漏的功能.最后也通过实际截获实验,验证了该方法的可行性.
[Abstract]:The electromagnetic radiation of the computer contains the information leakage caused by the video information. Based on the random scrambling, this paper proposes a complementary scrambling method according to the human visual effect to suppress the leakage of the video information passing through the electromagnetic radiation. By adding and subtracting random noise to each frame of adjacent video information, the visual observation effect of human eye cancels the interference of noise to the video image, and the definition of video image is ensured while the noise is superimposed. It also achieves the function of restraining the electromagnetic leakage of video information. Finally, the feasibility of the method is verified by the actual interception experiment.
