通过电磁辐射（通常称为“暴风雨”）泄露信息已被视为一种威胁，并已提出了应对措施。特别是，库恩和安德森开发了一个保护措施，风暴称为风暴字体。通过实验，我们已经调查和评估的Tempest字体的有效性。此外，我们提出了一个新的措施，基于类似的方法来防止成功的暴风雨攻击。虽然库恩和安德森使用傅立叶变换作为低通滤波器，我们的方法使用高斯滤波器，除了傅立叶变换。我们的实验结果表明，这种方法是更有效的。
Information leakage via electromagnetic emanation, usually known as Tempest, has been recognized as a threat and countermeasures have been proposed. In particular, Kuhn and Anderson developed a protective measure for Tempest called theTempest fonts. Through experiments, we have investigated and evaluated the effectiveness of the Tempest fonts. Furthermore, we propose a new measure based on a similar approach to prevent successful Tempest attacks. While Kuhn and Anderson use Fourier transformation as a low-pass filter, our approach uses a Gaussian filter in addition to Fourier transformation. Our experimental results show that this approach is more effective.
