Hardware-Based Methods for Electronic Device Protection against Invasive and Non-Invasive Attacks

Abstract

This paper reviews hardware-based protection methods for electronic devices, encompassing scientific publications and published patents. This review covers insights from the scientific community and innovative solutions patented in the industry. By combining these two sources, this paper offers a comprehensive and holistic review of electronic device security. Electronic devices are integral to modern life, but their widespread use invites security threats, both digital and physical. This paper reviews hardware-based protection methods against invasive and non-invasive attacks, emphasizing the importance of a dual approach through hardware design. Invasive attacks involve physical tampering, and we explore anti-tampering techniques such as conductive meshes, sensors and physically unclonable functions (PUFs). Non-invasive, side-channel attacks encompass various attack vectors, focusing on electromagnetic analysis. To counter these attacks, we analyze techniques like reducing and masking electromagnetic radiation. This paper bridges the gap between invasive and non-invasive attack mitigation. It underscores the necessity of a multifaceted approach to safeguard electronic devices in an interconnected world, preserving their reliability and functionality.

Protecting Data at Risk of Unintentional Electromagnetic Emanation: TEMPEST Profiling

“…The effectiveness of the eavesdropping barrier, however, is highly dependent on the interfering signal modulation pattern, so the interfering signal must be chosen very carefully [1]. This can be achieved by designing devices to reduce emissions at the component, system, circuit board, and device level [99].…”
