Coded Caching in the Presence of a Wire and a Cache Tapping Adversary of Type II
Mohamed Nafea, Aylin Yener
This paper introduces the notion of cache-tapping into the information theoretic models of coded caching. The wiretap channel II in the presence of multiple receivers equipped with…
Generalizing Multiple Access Wiretap and Wiretap II Channel Models: Achievable Rates and Cost of Strong Secrecy
Mohamed Nafea, Aylin Yener
In this paper, new two-user multiple access wiretap channel models are studied. First, the multiple access wiretap channel II with a discrete memoryless main channel, under three d…
A New Wiretap Channel Model and its Strong Secrecy Capacity
Mohamed Nafea, Aylin Yener
In this paper, a new wiretap channel model is proposed, where the legitimate transmitter and receiver communicate over a discrete memoryless channel. The wiretapper has perfect acc…
Secure Degrees of Freedom for the MIMO Wire-tap Channel with a Multi-antenna Cooperative Jammer
Mohamed Nafea, Aylin Yener
In this paper, a multiple antenna wire-tap channel in the presence of a multi-antenna cooperative jammer is studied. In particular, the secure degrees of freedom (s.d.o.f.) of this…
On the Diversity Gain Region of the Z-interference Channels
Mohamed S. Nafea, Karim G. Seddik, Mohammed Nafie +1
In this work, we analyze the diversity gain region (DGR) of the single-antenna Rayleigh fading Z-Interference channel (ZIC). More specifically, we characterize the achievable DGR o…
A Diversity-Multiplexing-Delay Tradeoff of ARQ Protocols in The Z-interference Channel
Mohamed S. Nafea, D. Hamza, Karim G. Seddik +2
In this work, we analyze the fundamental performance tradeoff of the single-antenna Automatic Retransmission reQuest (ARQ) Z-interference channel (ZIC). Specifically, we characteri…
