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…
