Robust proactive eavesdropping in UAV-enabled wireless communication networking [PDF]
EURASIP Journal on Wireless Communications and Networking, 2019 In this paper, we considered a robust beamforming design problem for a proactive eavesdropping via jamming, in which a full-duplex legitimate monitor tries to eavesdrop on a suspicious communication link between the secondary pairs in an unmanned aerial ...

Proactive Eavesdropping in Relaying Systems [PDF]
IEEE Signal Processing Letters, 2017 This paper investigates the performance of a legitimate surveillance system, where a legitimate monitor aims to eavesdrop on a dubious decode-and-forward relaying communication link. In order to maximize the effective eavesdropping rate, two strategies are proposed, where the legitimate monitor adaptively acts as an eavesdropper, a jammer or a helper ...

Covert Surveillance via Proactive Eavesdropping Under Channel Uncertainty [PDF]
IEEE Transactions on Communications, 2021 Surveillance performance is studied for a wireless eavesdropping system, where a full-duplex legitimate monitor eavesdrops a suspicious user’s link with artificial noise (AN) assistance. Different from the existing works, the suspicious receiver is assumed to be capable of detecting the presence of AN.

Jamming-Assisted Proactive Eavesdropping Over Two Suspicious Communication Links [PDF]
IEEE Transactions on Wireless Communications, 2020 This paper studies a new and challenging wireless surveillance problem where a legitimate monitor attempts to eavesdrop two suspicious communication links simultaneously. To facilitate concurrent eavesdropping, our multi-antenna legitimate monitor employs a proactive eavesdropping via jamming approach, by selectively jamming suspicious receivers to ...

Proactive eavesdropping via cognitive jamming in fading channels [PDF]
2016 IEEE International Conference on Communications (ICC), 2016 To enhance the national security, there is a growing need for government agencies to legitimately monitor suspicious communication links for preventing intended crimes and terror attacks. In this paper, we propose a new wireless information surveillance paradigm by investigating a scenario where a legitimate monitor aims to intercept a suspicious ...

IRS Backscatter‐Assisted Security Transmission against Proactive Eavesdropping
Wireless Communications and Mobile Computing, 2022 In this paper, we consider the IRS backscatter‐assisted physical layer security, aimed at countering smart eavesdroppers capable of sending jamming signals. Specifically, the eavesdropper increases the eavesdropping rate by sending jamming signals and is able to adjust the transmission strategy according to the received beamforming.

Proactive attack: A strategy for legitimate eavesdropping
2016 IEEE Sixth International Conference on Communications and Electronics (ICCE), 2016 In this paper, we study a novel approach to eavesdrop the messages of suspicious users for a surveillance purpose. In particular, we consider a scenario in which the legitimate monitor can act as a jamming source and a decode-and-forward relay station that can force the suspicious users to reveal their exchanged messages.
