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…
Keys through ARQ
Mohamed Abdel Latif, Ahmed Sultan, Hesham El Gamal
This paper develops a novel framework for sharing secret keys using the well-known Automatic Repeat reQuest (ARQ) protocol. The proposed key sharing protocol does not assume any pr…
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…
The MIMO Wireless Switch: Relaying Can Increase the Multiplexing Gain
Hassan Ghozlan, Yahya Mohasseb, Hesham El Gamal +1
This paper considers an interference network composed of K half-duplex single-antenna pairs of users who wish to establish bi-directional communication with the aid of a multi-inpu…
