Quantum Advantage in Locally Differentially Private Hypothesis Testing
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee +1
We consider a private hypothesis testing scenario, including both symmetric and asymmetric testing, based on classical data samples. The utility is measured by the error exponents,…
Optimal Regret Exponents for Bayesian Statistical Decision Problems
Hyun-Young Park, Si-Hyeon Lee
We study finite-state finite-action Bayesian statistical decision problems. While exact error-exponent characterizations are known for several special cases, including hypothesis t…
Training-Free Coverless Multi-Image Steganography with Access Control
Minyeol Bae, Si-Hyeon Lee
Coverless Image Steganography (CIS) hides information without explicitly modifying a cover image, providing strong imperceptibility and inherent robustness to steganalysis. However…
Optimal Privacy-Utility Trade-Offs in LDP: Functional and Geometric Perspectives
Seung-Hyun Nam, Hyun-Young Park, Si-Hyeon Lee
Local differential privacy (LDP) has emerged as a gold-standard framework for privacy-preserving data analysis. However, characterizing the optimal privacy-utility trade-off (PUT)…
Nonlocal and quantum advantages in network coding for multiple access channels
Jiyoung Yun, Seung-Hyun Nam, Hyun-Young Park +3
In this work, we consider two-sender, one-receiver communication over a discrete memoryless multiple-access channel without feedback, where two senders may cooperate on channel cod…
Secure Communications, Sensing, and Computing Towards Next-Generation Networks
Ruiqi Liu, Beixiong Zheng, Jemin Lee +4
Next-generation wireless networks are progressing beyond conventional connectivity to incorporate emerging sensing and computing capabilities. This convergence gives rise to integr…
