【摘要】:针对计算机的电磁辐射可能会包含视频信息从而造成信息泄漏的问题,分析了计算机数字视频接口的视频信息传输途径,建立了视频信息串行传输和并行传输路径相应的时/频域模型,获得串行传输和并行传输在传输不同视频信号时的辐射泄漏特征.结合视频信息截获与复现的原理,发现了串行传输灰度图像、并行传输黑白图像表现出假并真串而容易被截获的结论,并通过测试加以验证.
[Abstract]:Aiming at the problem that the electromagnetic radiation of computer may contain video information and cause information leakage, this paper analyzes the video information transmission way of computer digital video interface. The time / frequency domain model of serial transmission and parallel transmission path of video information is established, and the radiation leakage characteristics of serial transmission and parallel transmission are obtained when different video signals are transmitted. Based on the principle of video information capture and reproduction, the paper finds the conclusion that serial transmission grayscale image, parallel transmission black and white image shows false and true string and is easy to be intercepted, and it is verified by test.
