计算机视频信息的电磁辐射泄漏的截获难度分析

The Analysis of the Difficulty of Eavesdropping the Electromagnetic Leakage of Computer Video Signal

本文首先分析了计算机视频信息的电磁辐射泄漏(以下简称视频电磁泄漏)产生的机理,进而分析了影响其截获难度的因素,最后提出了减小视频电磁泄漏被截获的可能性的一些方法。

Firstly, the principle of the electromagnetic leakage of computer video signal was analyzed in this paper, Moreover, factors in the difficulty of eavesdropping the leakage were analyzed, At last, some methods of lowering the possibility of eavesdropping the leakage were brought forward.
