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…
