The Age of Information of Short-Packet Communications: Joint or Distributed Encoding?
Zhifeng Tang, Nan Yang, Parastoo Sadeghi +1
In this paper, we analyze the impact of different encoding schemes on the age of information (AoI) performance in a point-to-point system, where a source generates packets based on…
Offset-Symmetric Gaussians for Differential Privacy
Parastoo Sadeghi, Mehdi Korki
The Gaussian distribution is widely used in mechanism design for differential privacy (DP). Thanks to its sub-Gaussian tail, it significantly reduces the chance of outliers when re…
Enhancing Utility in the Watchdog Privacy Mechanism
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi +1
This paper is concerned with enhancing data utility in the privacy watchdog method for attaining information-theoretic privacy. For a specific privacy constraint, the watchdog meth…
On Converse Results for Secure Index Coding
Yucheng Liu, Lawrence Ong, Parastoo Sadeghi +2
In this work, we study the secure index coding problem where there are security constraints on both legitimate receivers and eavesdroppers. We develop two performance bounds (i.e.,…
Differential Privacy for Binary Functions via Randomized Graph Colorings
Rafael G. L. D'Oliveira, Muriel Medard, Parastoo Sadeghi
We present a framework for designing differentially private (DP) mechanisms for binary functions via a graph representation of datasets. Datasets are nodes in the graph and any two…
Information Leakage in Zero-Error Source Coding: A Graph-Theoretic Perspective
Yucheng Liu, Lawrence Ong, Sarah Johnson +3
We study the information leakage to a guessing adversary in zero-error source coding. The source coding problem is defined by a confusion graph capturing the distinguishability bet…
