Secure Offloading in NOMA-Aided Aerial MEC Systems Based on Deep Reinforcement Learning
Hongjiang Lei, Mingxu Yang, Ki-Hong Park +1
Mobile edge computing (MEC) technology can reduce user latency and energy consumption by offloading computationally intensive tasks to the edge servers. Unmanned aerial vehicles (U…
Secure Semantic Communications: From Perspective of Physical Layer Security
Yongkang Li, Zheng Shi, Han Hu +3
Semantic communications have been envisioned as a potential technique that goes beyond Shannon paradigm. Unlike modern communications that provide bit-level security, the eaves-dro…
Proactive Eavesdropping in Relay Systems via Trajectory and Power Optimization
Qian Dan, Hongjiang Lei, Ki-Hong Park +2
Wireless relays can effectively extend the transmission range of information. However, if relay technology is utilized unlawfully, it can amplify potential harm. Effectively survei…
Two Birds With One Stone: Beamforming Design for Target Sensing and Proactive Eavesdropping
Qian Dan, Hongjiang Lei, Ki-Hong Park +2
This work studies the beamforming design in the joint proactive eavesdropping (PE) and target sensing (TS) systems. The base station (BS) wiretaps the information transmitted by th…
Multi-UAV Trajectory Design for Fair and Secure Communication
Hongjiang Lei, Dongyang Meng, Haoxiang Ran +3
Unmanned aerial vehicles (UAVs) play an essential role in future wireless communication networks due to their high mobility, low cost, and on-demand deployment. In air-to-ground li…
3D Trajectory Design for Energy-constrained Aerial CRNs Under Probabilistic LoS Channel
Hongjiang Lei, Xiaqiu Wu, Ki-Hong Park +1
Unmanned aerial vehicles (UAVs) have been attracting significant attention because there is a high probability of line-of-sight links being obtained between them and terrestrial no…
Aerial Relay to Achieve Covertness and Security
Jiacheng Jiang, Hongjiang Lei, Ki-Hong Park +2
In this work, a delay-tolerant unmanned aerial vehicle (UAV) relayed covert and secure communication framework is investigated. In this framework, a legitimate UAV serves as an aer…
On Secure mmWave RSMA Systems
Hongjiang Lei, Sha Zhou, Xinhu Chen +4
This work considers a multiple-input-single-output mmWave RSMA system wherein a base station serves two users in the presence of a passive eavesdropper. Different eavesdropping sce…
