| 摘 要： | 计算机电磁泄漏信息的接收和重现对信息侦收和安全传输都具有重要意义。显示器上的信息是有用信息的最直接体现 ,而且很容易通过电磁辐射产生泄漏。通过无线接收显示器的电磁辐射信息并经过数据采集卡输入到计算机 ,实现了原始信息的还原处理。该系统适用面广 ,方便灵活 ,运行结果证明该方法是切实可行的。

| Abstract: | Receiving and recovering the electromagnetic (EM) radiation from computer has essential value for data interception and safe transmission. The messages on displayer denote directly the useful information of computer and may give away through EM radiation. In this paper, a new wireless system was designed to receive the radiated information, then the information was transmitted into a computer through A/D card and the original information was recovered. The measured results proved that the system was feasible and to be suit for any computer. |
