Randomization for Security in Half-Duplex Two-Way Gaussian Channels

Aly El Gamal, Moustafa Youssef, Hesham El Gamal

This paper develops a new physical layer framework for secure two-way wireless communication in the presence of a passive eavesdropper, i.e., Eve. Our approach achieves perfect inf…

ARQ Secrecy: From Theory to Practice

Yara Omar, Moustafa Youssef, Hesham El Gamal

Inspired by our earlier work on Automatic Repeat reQuest (ARQ) secrecy, we propose a simple, yet efficient, security overlay protocol to existing 802.11 networks. Our work targets…

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…
