Achieving the Exactly Optimal Privacy-Utility Trade-Off with Low Communication Cost via Shared Randomness
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee
We consider a discrete distribution estimation problem under a local differential privacy (LDP) constraint in the presence of shared randomness. By exploiting the shared randomness…
Trajectory Optimization for Cellular-Enabled UAV with Connectivity and Battery Constraints
Hyeon-Seong Im, Kyu-Yeong Kim, Si-Hyeon Lee
We address the path planning problem for a cellular-enabled unmanned aerial vehicle (UAV) considering both connectivity and battery constraints. The UAV's mission is to expeditious…
Exactly Optimal and Communication-Efficient Private Estimation via Block Designs
Hyun-Young Park, Seung-Hyun Nam, Si-Hyeon Lee
In this paper, we propose a new class of local differential privacy (LDP) schemes based on combinatorial block designs for discrete distribution estimation. This class not only rec…
Multi-User Cooperation for Covert Communication Under Quasi-Static Fading
Jinyoung Lee, Duc Trung Dinh, Hyeonsik Yeom +2
This work studies a covert communication scheme for an uplink multi-user scenario in which some users are opportunistically selected to help a covert user. In particular, the selec…
