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。
Computer electromagnetic leakage of information received and reproduced on the detection of information and secure transmission are of great significance. The information on the display is the most direct indication of useful information, and can easily be leaked by electromagnetic radiation. Through the wireless receiver of electromagnetic radiation information and through the data acquisition card input to the computer, to achieve the original information reduction. The system is applicable to a wide range of convenient and flexible, the results show that the method is feasible.
