With the rising importance of information security, the necessity of implementing better security measures in the physical layer as well as the upper layers is becoming increasing apparent. Given the development of more accurate and less expensive measurement devices, highperformance computers, and larger storage devices, the threat of advanced attacks at the physical level has expanded from the military and governmental spheres to commercial products. In this paper, we review the issue of information security degradation through electromagnetic (EM)-based compromising of security measures in the physical layer (i.e., EM information security). Owing to the invisibility of EM radiation, such attacks can be serious threats. We first introduce the mechanism of information leakage through EM radiation and interference and then present possible countermeasures. Finally, we explain the latest research and standardization trends related to EM information security.

With the advent of the Internet of Things (IoT), many electronic devices (e.g., smart meters, surveillance cameras, mobile devices, and multiple sensors) are interconnected. Each device gathers data and uploads it to servers via communication networks. Servers store the large volumes of received data in databases. Applications analyze this data and extract valuable information. Finally, based on this information, new services (in domains such as smart cities, public safety, e-commerce, medical, healthcare, or automobile) are provided. In this data flow, systems and applications in the upper layer trust the hardware in the lower layer, which includes data-gathering devices. If the collected information is intentionally modified by adversaries, services in the upper layer could be disrupted. Therefore, to ensure service continuity in the IoT, it is important to secure the hardware layer in which data are harvested and transmitted. In this paper, we focus on hardware-level security in IoT systems and classify the schemes proposed for physical security of IoT into three categories. We also provide examples for each of these and explain threats and countermeasures.

“…Some means of attacks such as invasive attacks, semi-invasive attacks and non-invasive attacks have been researched in the last several years. Corresponding countermeasures have also been developed by researchers all over the world [2,3,4,5]. However, existing protective techniques mainly focus on chip-level protection and few studies pay attention to system-level protection as primary safeguards.…”

Information system security has been in the spotlight of individuals and governments in recent years. Integrated Circuits (ICs) function as the basic element of communication and information spreading, therefore they have become an important target for attackers. From this perspective, system-level protection to keep chips from being attacked is of vital importance. This paper proposes a novel method based on a fringing electric field (FEF) sensor to detect whether chips are dismantled from a printed circuit board (PCB) as system-level protection. The proposed method overcomes the shortcomings of existing techniques that can be only used in specific fields. After detecting a chip being dismantled from PCB, some protective measures like deleting key data can be implemented to be against attacking. Fringing electric field sensors are analyzed through simulation. By optimizing sensor’s patterns, areas and geometrical parameters, the methods that maximize sensitivity of fringing electric field sensors are put forward and illustrated. The simulation is also reproduced by an experiment to ensure that the method is feasible and reliable. The results of experiments are inspiring in that they prove that the sensor can work well for protection of chips and has the advantage of universal applicability, low cost and high reliability.
