S Vuppala, G Abreu - IEEE Systems Journal, 2016 - ieeexplore.ieee.org
We perform an analysis of the secrecy outage and transmission capacity of random networks under Nakagami-m fading with colluding eavesdroppers, in the asymptotic case of …

Correlation between the legitimate receiver and the eavesdropper has been seldom considered in the literature when evaluating secrecy metrics in stochastic wireless networks …
Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of the propagation …
PC Pinto, J Barros, MZ Win - IEEE Transactions on Information …, 2011 - ieeexplore.ieee.org
The ability to exchange secret information is critical to many commercial, governmental, and military networks. Information-theoretic security-widely accepted as the strictest notion of …
W Liu, Z Ding, T Ratnarajah… - IEEE Transactions on …, 2015 - ieeexplore.ieee.org
In this paper, we investigate physical-layer security in a random wireless network where both legitimate and eavesdropping nodes are randomly deployed. In the first scenario, we …
S Vuppala, G Abreu - … on Personal, Indoor, and Mobile Radio …, 2013 - ieeexplore.ieee.org
We investigated the secrecy outage of unicast channels in random networks exposed to unknown numbers of randomly located eavesdroppers, obtaining original expressions …
This paper studies the achievable secure rate per source-destination pair in wireless networks. First, a path loss model is considered, where the legitimate and eavesdropper …
J Zhu, Y Chen, Y Shen, O Takahashi, X Jiang… - Ad hoc networks, 2014 - Elsevier
This paper considers the transmission of confidential messages over noisy wireless ad hoc networks, where both background noise and interference from concurrent transmitters affect …
S Vuppala, G Abreu - 2013 Asilomar Conference on Signals …, 2013 - ieeexplore.ieee.org
We investigate the secrecy transmission capacity of random networks with Nakagami-m fading. Using a model that accounts for uncertainties both in node locations (distances) and …
