Covert Communication with Cognitive Jammer Embedded in Public Communication System [PDF]
SensorsIn this work, we investigate covert communication with a cognitive jammer (CJ) embedded in a public communication system. Specifically, while the transmitter continuously transmits public messages to the receiver, it may also transmit its covert messages

Covert Communication With Relay Selection [PDF]
IEEE Wireless Communications Letters, 2021 In this letter, we investigate covert communication in relay networks with relay selection. We consider the scenario that while forwarding the source’s message, the selected relay opportunistically transmits its own message to the destination covertly. We derive the probability of detection error (PDE) and the average covert rate (ACR) in a closed form,

A Multi-Dimensional Covert Transaction Recognition Scheme for Blockchain
Mathematics, 2023 Covert communication was widely studied in recent years in terms of keeping the communication of entities on the Internet secret from the point of view of information security. Due to the anonymity of accounts and the publicness of the ledger, blockchain

Covert Communication With Mismatched Decoders
IEEE Transactions on Information Theory, 2022 This paper considers the problem of covert communication with mismatched decoding, in which a sender wishes to reliably communicate with a receiver whose decoder is fixed and possibly sub-optimal, and simultaneously to ensure that the communication is covert with respect to a warden.

Covert Channel Communication as an Emerging Security Threat in 2.5D/3D Integrated Systems
Sensors, 2023 In this paper, first, a broad overview of existing covert channel communication-based security attacks is provided. Such covert channels establish a communication link between two entities that are not authorized to share data. The secret data is encoded

Covert Quantum Communication [PDF]
Physical Review Letters, 2016 We extend covert communication to the quantum regime by showing that covert quantum communication is possible over optical channels with noise arising either from the environment or from the sender's lab. In particular, we show that sequences of qubits can be transmitted covertly by using both a single photon and a coherent state encoding. We study the
