Joint Secrecy and Covert Communication (JSACC): An Enhanced Physical Layer Security Approach
In this paper, we propose an enhanced physical layer security approach, named joint secrecy and covert communication JSACC, which aims to improve the performance of physical layer security PLS. The JSACC system can dynamically switch between secrecy mode and covert mode according to the channel...
Navigating the Dual-Use Nature and Security Implications of Reconfigurable Intelligent Surfaces in Next-Generation Wireless Systems
Reconfigurable intelligent surface RIS technology offers significant promise in enhancing wireless communication systems, but its dual-use potential also introduces substantial security risks. This survey explores the security implications of RIS in next-generation wireless networks. We first...
Encoded Jamming Secure Communication for RIS-Assisted and ISAC Systems
This paper considers a cooperative jamming CJ-aided secure wireless communication system. Conventionally, the jammer transmits Gaussian noise GN to enhance security; however, the GN scheme also degrades the legitimate receiver's performance. Encoded jamming EJ mitigates this interference but does...
Antifragility of RIS-Assisted Communication Systems under Jamming Attacks
Antifragility of communication systems is defined as measure of benefits gained from the adverse events and variability of its environment. In this paper, we introduce the notion of antifragility in Reconfigurable Intelligent Surface RIS assisted communication systems affected by a jamming attack...
