The Two-Way Wiretap Channel: Achievable Regions and Experimental Results
Aly El Gamal, O. Ozan Koyluoglu, Moustafa Youssef +1
This work considers the two-way wiretap channel in which two legitimate users, Alice and Bob, wish to exchange messages securely in the presence of a passive eavesdropper Eve. In t…
Keys through ARQ: Theory and Practice
Yara Abdallah, Mohamed Abdel Latif, Moustafa Youssef +2
This paper develops a novel framework for sharing secret keys using the Automatic Repeat reQuest (ARQ) protocol. We first characterize the underlying information theoretic limits,…
HyberLoc: Providing Physical Layer Location Privacy in Hybrid Sensor Networks
Rania El-Badry, Ahmed Sultan, Moustafa Youssef
In many hybrid wireless sensor networks' applications, sensor nodes are deployed in hostile environments where trusted and un-trusted nodes co-exist. In anchor-based hybrid network…
Distributed Flooding-based Storage Algorithms for Large-scale Sensor Networks
Salah A. Aly, Hager S. Darwish, Moustafa Youssef +1
In this paper we propose distributed flooding-based storage algorithms for large-scale wireless sensor networks. Assume a wireless sensor network with nodes that have limited p…
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…
