“…The radio broadcasts are more vulnerable due to the open wireless air interface for the communications environment. Physical layer secrecy is based on information-theoretic principles and takes advantage of physical propagation characteristics, such as interference, fading, and noise, to protect the confidentiality of the transmission in the face of the threat posed by the development of powerful computing technologies that can be realized through cryptographic encryption [33].…”

The leitmotif of this paper aims at providing an architecture for the age of information (AoI) and cache-assisted hybrid multicast/unicast/device-to-device (D2D) transmission with the promising cell-free massive multiple-input multiple-output (MIMO) technology, for enriching data transmission rate, slackening the burden of high-volume data traffic, and boosting the system efficiency. Then, we design the user-centric transmission scheme and talk about the feasibility of the preliminary solutions for the multigroup multicast, D2D, wireless caching, and AoI, typically for signal processing, transmission mode selection mechanism, and cache replacement strategy. Finally, we also shall afford a viable research prediction containing an ensemble of the potential challenges and promising research directions to set the path for re-inventing an efficient sixth-generation (6G) communication system.

“…Many schemes have been proposed to secure the transmission, among which the physical layer security (PLS) achieves the confidentiality of the communication by exploiting the stochastic time-varying properties of the channel [2][3][4][5][6]. In contrast to traditional cryptography techniques, physical layer security techniques do not require any additional security schemes or algorithms to be implemented in other layers above the physical layer [7,8].…”

Reconfigurable intelligent surface (RIS) has great potential in securing wireless transmission, and it can flexibly change the wireless communication environment. However, the employment of RIS increases the difficulty in beamforming of base station (BS), and existing schemes cannot be directly utilized to enhance the security of system. Therefore, a reinforcement learning framework to jointly control BS and RIS for the purpose of enhancing the secure performance is proposed. Specifically, the beamforming ia transformed with artificial noise and reflection control as a Markov decision problem (MDP) in complex domain. Then, we develop the deep deterministic policy gradient based on complex‐valued neural networks (CV‐DDPG) to imitate the rules of complex computation. Additionally, the CV‐DDPG is performed as the agent of reinforcement learning to control the BS and RIS, which enables better utilization of the implied phase information of complex values in the system. The simulation results show that the proposed model promotes the performance of the control and greatly improves the secrecy rate of the legitimate user.

This paper investigates the problem of buffer-aided relay selection to achieve reliable and secure communications in a two-hop amplify-and-forward (AF) network with an eavesdropper. Due to the fading of wireless signals and the broadcast nature of wireless channels, transmitted signals over the network may be undecodable at the receiver end or have been eavesdropped by eavesdroppers. Most available buffer-aided relay selection schemes consider either reliability or security issues in wireless communications; rarely is work conducted on both reliability and security issues. This paper proposes a buffer-aided relay selection scheme based on deep Q-learning (DQL) that considers both reliability and security. By conducting Monte Carlo simulations, we then verify the reliability and security performances of the proposed scheme in terms of the connection outage probability (COP) and secrecy outage probability (SOP), respectively. The simulation results show that two-hop wireless relay network can achieve reliable and secure communications by using our proposed scheme. We also performed comparison experiments between our proposed scheme and two benchmark schemes. The comparison results indicate that our proposed scheme outperforms the max-ratio scheme in terms of the SOP.
