Generalization of the Fano and Non-Fano Index Coding Instances
Arman Sharififar, Parastoo Sadeghi, Neda Aboutorab
Matroid theory is fundamentally connected with index coding and network coding problems. In fact, the reliance of linear index coding and network coding rates on the characteristic…
On the Optimality of Linear Index Coding over the Fields with Characteristic Three
Arman Sharififar, Parastoo Sadeghi, Neda Aboutorab
It has been known that the insufficiency of linear coding in achieving the optimal rate of the general index coding problem is rooted in its rate's dependency on the field size. Ho…
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.,…
Broadcast Rate Requires Nonlinear Coding in a Unicast Index Coding Instance of Size 36
Arman Sharififar, Parastoo Sadeghi, Neda Aboutorab
Insufficiency of linear coding for the network coding problem was first proved by providing an instance which is solvable only by nonlinear network coding (Dougherty et al., 2005).…
An Update-based Maximum Column Distance Coding Scheme for Index Coding
Arman Sharififar, Neda Aboutorab, Parastoo Sadeghi
In this paper, we propose a new scalar linear coding scheme for the index coding problem called update-based maximum column distance (UMCD) coding scheme. The central idea in each…
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…
