Network-Controlled Physical-Layer Security: Enhancing Secrecy Through Friendly Jamming
Sayed Amir Hoseini, Parastoo Sadeghi, Faycal Bouhafs +2
The broadcasting nature of the wireless medium makes exposure to eavesdroppers a potential threat. Physical Layer Security (PLS) has been widely recognized as a promising security…
Asymmetric Local Information Privacy and the Watchdog Mechanism
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi
This paper proposes a novel watchdog privatization scheme by generalizing local information privacy (LIP) to enhance data utility. To protect the sensitive features correlated…
Information Leakage in Index Coding With Sensitive and Non-Sensitive Messages
Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3
Information leakage to a guessing adversary in index coding is studied, where some messages in the system are sensitive and others are not. The non-sensitive messages can be used b…
Information Leakage in Index Coding
Yucheng Liu, Lawrence Ong, Phee Lep Yeoh +3
We study the information leakage to a guessing adversary in index coding with a general message distribution. Under both vanishing-error and zero-error decoding assumptions, we dev…
Heterogeneous Differential Privacy via Graphs
Sahel Torkamani, Javad B. Ebrahimi, Parastoo Sadeghi +2
We generalize a previous framework for designing utility-optimal differentially private (DP) mechanisms via graphs, where datasets are vertices in the graph and edges represent dat…
Rainbow Differential Privacy
Ziqi Zhou, Onur Günlü, Rafael G. L. D'Oliveira +3
We extend a previous framework for designing differentially private (DP) mechanisms via randomized graph colorings that was restricted to binary functions, corresponding to colorin…
