摘要

作者概述了计算设备作为电磁(EM)发射源的机制，其中包含通过各种途径(导电或辐射或两者兼而有之)从源传导的信息。简要概述了用于显示从源处辐射出去的信息的接收器。接收器仅使用商业组件构建。该装置足够灵敏，可以截获距离辐射源50米远的辐射信号。

Advances in understanding of EM emissions from computing devices

The authors outline mechanisms by which computing equipment acts as a source of electromagnetic (EM) emissions containing information conducted away from the source through various paths (conductive or radiative or both). A brief summary is given of a receiver to display the information that has radiated away from the source. The receiver is constructed using only commercial components. The device is sensitive enough to intercept radiated signals as much as 50 m from the source.<>
