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 …

Covert communications have arisen as an effective communications security measure that
overcomes some of the limitations of cryptography and physical layer security. The main …

In this paper, the covert communication is considered with a full-duplex (FD) receiver under
covertness and reliability constraints in the finite blocklength regime. Conventional covert …

With the rapid development of wireless network technology, wireless communication system
effectively satisfies the demand for personal communication and information acquisition …

Covert communication enforces the transmitted signal to be indistinguishable from other
signals under wireless environment, making it difficult for an eavesdropper to detect and …
