In this paper, we investigate the performance of covert communications in different types of a
relay system: decode-and-forward (DF), compress-and-forward (CF) and amplify-and …

This paper focuses on the covert communication in a two-hop relay system consisting of a
transmitter, a relay, a receiver and a warden, where the relay can flexibly select between the …

In this paper, we study covert communications strategies in a compress-and-forward (CF)
relay system. Along with a public message to a destination node via a CF relay, a source …

Physical layer key generation (PLKG) can significantly enhance the security of classic
encryption schemes by efficiently providing secret keys in resource-limited network like the …

Due to the inherent characteristics of system extensibility and implementation flexibility,
unmanned aerial vehicle (UAV)-assisted data aggregations will play an essential role in …

This paper investigates the covert performance of the finite block length device-to-device
(D2D) transmission between the multi-antenna transceivers assisted by a decode-and …

In wireless communications, eavesdropping is a threat due to the broadcast nature of the
channel. Therefore, in addition to the rate and the error probability, the secrecy level should …

Physical layer security was designed as an effective solution to provide the security and
confidentiality of information transmission in wireless networks, and secrecy transmission …

The wireless communication of unmanned aerial vehicles (UAVs) has attracted a lot of
interest for reasons such as the possibility of high mobility, low-cost, deployment based on …
