摘　　要：信息技术设备会产生电磁泄漏,泄漏的电磁信号会还原为有用的信息,造成泄密。以计算机系统为核心的信息技术设备电磁发射与信息泄漏问题为对象,分析有关电磁泄漏的途径和机理,并提出了防电磁泄漏方法。The information technology equipment may produce electromagnetic leakage; the electromagnetic signal can be restored ; thus the confidential matters can betrayed through electromagnetic leakage. The mechanism of the electromagnetic leakage from information technology equipment was analyzed by taking important attentions to the computer system. The methods of anti - electromagnetic leakage from the information technology equipment were put forward.
