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…
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…
Protograph LDPC Code Design for Asynchronous Random Access
Federico Clazzer, Balazs Matuz, Sachini Jayasooriya +2
This work addresses the physical layer channel code design for an uncoordinated, frame- and slot-asynchronous random access protocol. Starting from the observation that collisions…
Centralized Caching with Unequal Cache Sizes
Behzad Asadi, Lawrence Ong, Sarah J. Johnson
We address a centralized caching problem with unequal cache sizes. We consider a system with a server of files connected through a shared error-free link to a group of cache-enable…
New Density Evolution Approximation for LDPC and Multi-Edge Type LDPC Codes
Sachini Jayasooriya, Mahyar Shirvanimoghaddam, Lawrence Ong +2
This paper considers density evolution for lowdensity parity-check (LDPC) and multi-edge type low-density parity-check (MET-LDPC) codes over the binary input additive white Gaussia…
