摘要
计算机显示器(visualdisplayunit-VDU)的电磁发射会导致视频信息泄漏,该文提出一种用于侦收VDU信息泄漏的模拟-数字综合系统,理论分析了VDU电磁发射的接收和视频信号的重建,给出了实验测试结果和信号重建实例,说明该系统可有效应用于对计算机系统的信息攻击。
Electromagnetic emanations from computer VDU can lead to video information leakage.A novel analog-digital intercepting system is presented in this paper,followed by theoretical analysis of interception and reconstruction of video information.Test results and a reconstructed example are given.The method described here is efficient in information attack on computer system.
