众所周知，在个人计算机和智能卡等IT设备中，电磁辐射与信息处理之间存在着关系。在本文中，我们展示了如何估计由于电磁辐射而泄露的信息量和平均化技术的有效性。我们假设IT设备和接收器之间的区域是一个通信通道，并根据其通道容量定义通过电磁辐射泄漏的信息量。并估算了窃听者通过电磁辐射所能获得的最大信息量。通过使用这些估计，我们得到了有效的平均技术所需的数据量。
It is well known that there is relationship between electromagnetic emanation and processing information in IT devices such as personal computers and smart cards. In this paper, we show how to estimate amount of information that is leaked as electromagnetic emanation and effectiveness of averaging technique. We assume the area between the IT device and the receiver is a communication channel, and we define the amount of information leakage via electromagnetic emanations by its channel capacity. And we also estimate the maximum amount of information which eavesdropper can get via electromagnetic emanation. By using these estimations, we derive the necessary amount of data for effective averaging technique.
