On Secrecy Capacity Scaling in Wireless Networks
O. Ozan Koyluoglu, C. Emre Koksal, Hesham El Gamal
This work studies the achievable secure rate per source-destination pair in wireless networks. First, a path loss model is considered, where the legitimate and eavesdropper nodes a…
Opportunistic Secrecy with a Strict Delay Constraint
Karim Khalil, O. Ozan Koyluoglu, Hesham El Gamal +1
We investigate the delay limited secrecy capacity of the flat fading channel under two different assumptions on the available transmitter channel state information (CSI). The first…
Cooperative encoding for secrecy in interference channels
O. Ozan Koyluoglu, Hesham El Gamal
This paper investigates the fundamental performance limits of the two-user interference channel in the presence of an external eavesdropper. In this setting, we construct an inner…
On the Secrecy Rate Region for the Interference Channel
O. Ozan Koyluoglu, Hesham El Gamal
This paper studies interference channels with security constraints. The existence of an external eavesdropper in a two-user interference channel is assumed, where the network users…
On the Delay Limited Secrecy Capacity of Fading Channels
Karim Khalil, Moustafa Youssef, O. Ozan Koyluoglu +1
In this paper, the delay limited secrecy capacity of the flat fading channel is investigated under two different assumptions on the available transmitter channel state information…
