Physical Layer Security in Reconfigurable Intelligent Surfaces enabled Wireless Communications Systems

About this Research Topic

The demand for higher reliability, data rates, energy efficiency, spectrum efficiency, and better coverage for future wireless communication networks has been rapidly increasing. A variety of wireless technologies have been introduced for such networks, including cooperative relaying, cognitive radio, multiple-input-multiple-output (MIMO), non-orthogonal multiple access (NOMA), etc. However, these technologies face several challenges as they operate in unfavorable wireless propagation environments. To this end, reconfigurable intelligent surfaces (RIS) have emerged as one of the potential techniques to enable the control of wireless environments via their unique functionalities (anomalous reflection, phase modification) and to meet such unprecedented requirements. Nevertheless, owing to the open nature of the wireless medium, the wireless systems are at risk of various malicious attacks (eavesdropping, jamming). Physical layer security (PHY-security) techniques have attracted widespread interest in the research community to circumvent these attacks. They leverage the physical characteristics of the wireless propagation environment and are committed to realizing perfect secure communications. Therefore, PHY-security analysis for RIS-enabled wireless communication systems is indeed necessary.

It is essential to design and develop some flexible, versatile, and inclusive physical layer solutions to support various demands of next-generation wireless communications systems. Numerous key enabling physical layer technologies, such as cognitive radio, cooperative relaying communications, massive MIMO, millimeter-wave (mmWave), NOMA, and so on, have been introduced. Still, the overall progress has been relatively slow because of the deteriorating characteristics of the channel. RISs have received focused attention due to their significant capability in enabling an intelligent and controllable wireless propagation environment. In different technical works, various research efforts were put on the design, demonstration, and analysis of RIS-enabled physical layer technologies. However, efforts are still required to solve a number of open problems. Also, one of the major concerns of these RIS-enabled wireless communications systems is security against various malicious attacks, such as eavesdropping, spoofing, and jamming. PHY-security solutions are widely adopted to provide a secure infrastructure for wireless communications networks. However, their exploitation in securing RIS-enabled wireless systems has not been fully addressed. Therefore, it is interesting to thoroughly and comprehensively analyze the PHY-security in RIS-enabled wireless communications systems. The research topic welcomes all the researchers from both academia and industry to explore new innovative ideas and concepts for secure communications in RIS-enabled wireless systems.

The themes of interest for this research topic include, but are not limited to:

1. PHY-security in RIS-enabled cooperative relaying communications
2. PHY-security in RIS-enabled MIMO communications
3. PHY-security in RIS-enabled NOMA networks
4. PHY-security in RIS-enabled in multi-user MIMO communications
5. PHY-security in RIS-enabled in unmanned aerial vehicles (UAVs) communications
6. Machine learning and stochastic geometry-based solutions for PHY-security in RIS-enabled wireless communications systems
7. Artificial Noise based PHY-security solution in RIS-enabled wireless communications systems
8. RIS enhanced PHY-security for intelligent spectrum sensing and cognitive radio realization
9. PHY-security in RIS-enabled vehicular communications
10. Performance analysis of PHY-security in RIS-aided wireless communications systems over generalized fading channels
