Covert Channel Communication as an Emerging Security Threat in 2.5D/3D Integrated Systems [PDF]
Sensors, 2023 In this paper, first, a broad overview of existing covert channel communication-based security attacks is provided. Such covert channels establish a communication link between two entities that are not authorized to share data. The secret data is encoded
