摘要
信息设备在工作状态下LED指示器所发出的光信号可能会含有信息设备正在处理的信息 .为此对LED的信息泄密的原理进行了初步研究 。
Under certain conditions, LED status indicators on data information communication equipment are shown to carry optical signal that could correlate with information being processed by device. This paper shows the basic study about the idea of information leakage from LED and how to design an eavesdropping experiment, and describes design changes that can block this kind of compromising emanations. Finally some directions of this subject for future work are discussed.
