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…
Cooperative Jamming for Physical Layer Security Enhancement Using Deep Reinforcement Learning
Sayed Amir Hoseini, Faycal Bouhafs, Neda Aboutorab +2
Wireless data communications are always facing the risk of eavesdropping and interception. Conventional protection solutions which are based on encryption may not always be practic…
Network-Controlled Physical-Layer Security: Enhancing Secrecy Through Friendly Jamming
Sayed Amir Hoseini, Parastoo Sadeghi, Faycal Bouhafs +2
The broadcasting nature of the wireless medium makes exposure to eavesdroppers a potential threat. Physical Layer Security (PLS) has been widely recognized as a promising security…
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).…
