Study, design and realization of Electromagnetic Shielding using Metamaterials to counter Side-Channel Attacks.

Electromagnetic signals generated by devices during their operations can contain critical information, making them vulnerable to attacks that exploit these emissions in order to compromise the security. The study and effective management of these signals are essential to understand and mitigate the risks associated with those attacks, and to protect data privacy and security. Side-channel attacks represent an advanced form of cyber threat that exploits auxiliary information, such as the electromagnetic signals emitted by the devices during their operation, in order to extract sensitive data. This methodology highlights the need for cybersecurity strategies that not only protect data in the digital domain, but also consider the impact of physical signals emitted by devices. Shielding electromagnetic signals using metamaterials represents an innovative approach to mitigate this type of attacks. Metamaterials are engineered materials capable of manipulating the propagation of EM waves. Through their application, it becomes possible to control and reduce the detectability and accessibility of EM emissions from devices, offering new opportunities to design advanced and adaptable security systems. This study explores the implications of side-channel attacks, with a particular focus on the EM signals emitted by devices, and proposes a potential solution through the use of metamaterials, in order to enhance the security and resilience of computer systems.
