摘要

电磁攻击(EMA)对包含秘密信息的嵌入式设备构成了真正的威胁。这种攻击非常令人担忧，因为它们完全是被动的，成本低，而且在实践中很容易安装。在本文中，我们提出了两种创新技术，通过减少成功攻击密码实现所需的测量次数来增强电磁攻击。第一种方法是基于电磁屏蔽理论，旨在降低外部噪声源的贡献。而第二部分则提供了一种使用卡尔曼滤波(KF)预处理电磁信号的算法解决方案。

Techniques for electromagnetic attacks enhancement

Electromagnetic attacks (EMA) pose real threats to embedded devices containing a secret information. Such attacks are of great concern since they are completely passive, low cost and easily mounted in practice. In this paper, we propose two innovative techniques to enhance electromagnetic attacks by reducing the number of measurements needed to succeed an attack on cryptographic implementations. The first method is based on the electromagnetic shielding theory which aims at decreasing the contribution of external noise sources. Whereas, the second provides an algorithmic solution to preprocess electromagnetic signals using the Kalman filtering (KF).
