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…

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.,…

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…

A Linear Reduction Method for Local Differential Privacy and Log-lift

Ni Ding, Yucheng Liu, Farhad Farokhi

This paper considers the problem of publishing data while protecting correlated sensitive information . We propose a linear method to generate the sanitized data with th…

Independent User Partition Multicast Scheme for the Groupcast Index Coding Problem

Arman Sharififar, Neda Aboutorab, Yucheng Liu +1

The groupcast index coding (GIC) problem is a generalization of the index coding problem, where one packet can be demanded by multiple users. In this paper, we propose a new coding…

Secure Index Coding with Security Constraints on Receivers

Yucheng Liu, Parastoo Sadeghi, Neda Aboutorab +1

Index coding is concerned with efficient broadcast of a set of messages to receivers in the presence of receiver side information. In this paper, we study the secure index coding p…

Privacy-Utility Tradeoff in a Guessing Framework Inspired by Index Coding

Yucheng Liu, Ni Ding, Parastoo Sadeghi +1

This paper studies the tradeoff in privacy and utility in a single-trial multi-terminal guessing (estimation) framework using a system model that is inspired by index coding. There…

Generalized Alignment Chain: Improved Converse Results for Index Coding

Yucheng Liu, Parastoo Sadeghi

In this paper, we study the information-theoretic converse for the index coding problem. We generalize the definition for the alignment chain, introduced by Maleki et al., to captu…

Capacity Theorems for Distributed Index Coding

Yucheng Liu, Parastoo Sadeghi, Fatemeh Arbabjolfaei +1

In index coding, a server broadcasts multiple messages to their respective receivers, each with some side information that can be utilized to reduce the amount of communication fro…

On the Capacity for Distributed Index Coding

Yucheng Liu, Parastoo Sadeghi, Fatemeh Arbabjolfaei +1

The distributed index coding problem is studied, whereby multiple messages are stored at different servers to be broadcast to receivers with side information. First, the existing c…
