Physical Layer Covert Communication in B5G Wireless Networks—its Research, Applications, and Challenges

Yu'e Jiang, Liangmin Wang, Hsiao‐Hwa Chen +1 more

Physical layer covert communication is a crucial secure communication technology that enables a transmitter to convey information covertly to a recipient without being detected by adversaries. Unlike typical cryptography and physical layer security systems that concentrate on protecting the sent signal content, covert communications seek to conceal the existence of legitimate transmission. Thus, with beyond fifth-generation (B5G) wireless communications, covert communications can operate in tandem or as a supplement to conventional security techniques. We provide an extensive overview of the basic theories and several strategies in physical layer covert communications in this article. In particular, we go into great detail about the basic theories of physical layer covert communications, such as channel models, codes, secret keys, and covertness metrics, as well as various covert schemes in progressively more complicated scenarios, such as covert communications in single-antenna and multiantenna three-node systems and covert communications in jammer-and relay-aided systems. In addition, we identify the challenges and future directions for research on covert communications in B5G wireless networks.

On the use of massive cylindrical antenna arrays for physical layer security

Elias E. Yaacoub

The need for physical layer security techniques is increasing with the deployments of machine to machine (M2M), internet of things (IoT), and device to device (D2D) communications. An important aspect of physical layer security is to perform covert communications of a possibly unencrypted signal without allowing an eavesdropper to detect the signal. In this paper, cylindrical antenna arrays with a large number of elements are proposed in order to reach this objective. These arrays allow the transmission of both the useful signal to the destination and the jamming signal to the eavesdropper without resorting to the help of other nodes for relaying the signal and/or jamming the eavesdropper. In addition, these arrays can be used at the destination for enhancing the received signal level and/or jamming the eavesdropper simultaneously with the transmitter. Monte Carlo simulation results show that high levels of secrecy capacity can be achieved with the proposed approach.

Covert Communications Versus Physical Layer Security.

Moslem Forouzesh, Paeiz Azmi, Nader Mokari +1 more

This letter studies and compares the physical-layer security approach and the covert communication approach for a wiretap channel with a transmitter, an intended receiver and an eavesdropper. In order to make the comparison, we investigate the power allocation problems for maximizing the secrecy/covert rate subject to the transmit power constraint. Simulation results illustrate that if the eavesdropper is not noisy or it is near to the transmitter, covert communication is more preferable.
