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.

关键词: 视频信息, 电磁泄漏, 信息安全, 互补置乱

Abstract: The electromagnetic radiation of computer contains video information which causes the information leakage.In this paper,a method is proposed according to the effect of human visual,based on the random scrambling,which called complementary scrambling,for preventing the leakage of video information through the electromagnetic radiation.The effect of human visual can eliminate the interference of noise to video image by adding and subtracting the random noise to each contiguous frame of video information,and imposes noise on displayed screen images while keeping the quality of the image.And realize the function of preventing the video information electromagnetic leakage.Finally,the feasibility of the method is verified by experiments.

Key words: video information, electromagnetic leakage, information security, complementary scrambling
