ARQ Security in Wi-Fi and RFID Networks
Mohamed Elsabagh, Yara Abdallah, Moustafa Youssef +1
In this paper, we present two practical ARQ-Based security schemes for Wi-Fi and RFID networks. Our proposed schemes enhance the confidentiality and authenticity functions of these…
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,…
Polar Coding for Secure Transmission and Key Agreement
O. Ozan Koyluoglu, Hesham El Gamal
Wyner's work on wiretap channels and the recent works on information theoretic security are based on random codes. Achieving information theoretical security with practical coding…
A New Class of TAST Codes With A Simplified Tree Structure
Mohamed Oussama Damen, Hesham El Gamal, Ahmed A. Badr
We consider in this paper the design of full diversity and high rate space-time codes with moderate decoding complexity for arbitrary number of transmit and receive antennas and ar…
