Security Region Analysis with Artificial Noise Based on Secrecy Outage Probability

MILCOM 2018 - 2018 IEEE Military Communications Conference (MILCOM), 2018
This paper analyzes security region with artificial noise (AN) based on secrecy outage probability under the assumption that the eavesdropper's channel state information and location are unknown to the transceiver. By utilizing beamforming, the legitimate receiver transmits the AN in the direction of the legitimate transmitter to impair the ...

Secrecy outage probability of cooperative network through distributed Alamouti code

2015 IEEE 26th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2015
Abstract--- The cooperative diversity technique combined with distributed space-time coding can efficiently improve the secrecy capacity and transmission reliability of wireless communication systems. In this paper, a multicast cooperative relaying system based on distributed Alamouti space-time coding was considered, in order to jam an eavesdropper ...

Exact Outage Probability of Cooperative Secrecy Transmission: Impact of Unavailable Relays

Wireless Personal Communications, 2015
The impact of unavailable relays is a serious issue in cooperative communication schemes, where the operation state of relays affects optimal relay selection. In addition, secure signal transmission is an interesting approach to prevent the wiretapping actions of eavesdropper nodes in a wireless environment.

Secrecy Outage Probability of Multiuser Untrusted Amplify-and-Forward Relay Networks

2017 IEEE 85th Vehicular Technology Conference (VTC Spring), 2017
This paper investigates the effect of untrusted relay on the secrecy outage probability of amplify- and-forward relay networks with the help of direct links and multiple users. We consider three selection criteria which are based on the direct and relaying link. The impacts of both the direct and relaying links on SOP performance is studied by deriving

Secrecy Outage Probability for MRC Receiver in Presence of Multiple Antenna Eavesdropper

2018 IEEE 13th International Conference on Industrial and Information Systems (ICIIS), 2018
In this paper, we consider a hybrid fading model in which line of sight (LOS) component is available between the transmitter and legitimate receiver and assume that eavesdropper is not in LOS from the transmitter. We analyze probability of existence of secrecy and secrecy outage probability for the case that the channels to the legitimate receiver are $

Secrecy Outage Probability Analysis over Malaga-Malaga Fading Channels

2018 IEEE International Conference on Communications (ICC), 2018
As a novel statistical model, Malaga distribution is proposed recently, which covers many commonly used fading models as special cases. The secure transmission of information over the Malaga fading channels has not been discussed in literature.

Outage probability and secrecy capacity of a non-orthogonal multiple access system

2017 11th International Conference on Signal Processing and Communication Systems (ICSPCS), 2017
In this paper, we analyze the outage probability and secrecy capacity of a non-orthogonal multiple access (NOMA) system in the presence of an eavesdropper. In order to enhance spectral efficiency, a base station communicates with two users simultaneously in the same frequency band by superpimposing the transmit signals to the users in the power domain.

Secrecy outage probability and jamming coverage of UAV-enabled friendly jammer

2017 11th International Conference on Signal Processing and Communication Systems (ICSPCS), 2017
In this paper, we examine the secrecy performance of an unmanned aerial vehicle (UAV) equipped with an air-to-ground jammer and a ground communications network comprising a legitimate transmitter-receiver pair and an eavesdropper. We consider two scenarios: stationary UAV jammer and mobile UAV jammer. In the first scenario, we derive the secrecy outage

Minimization of Secrecy Outage Probability with Single-Antenna Uncoordinated Cooperative Jamming

2019 IEEE Global Communications Conference (GLOBECOM), 2019
The problem of power allocation with uncoordinated cooperative jamming is addressed in this paper to enhance the physical layer security of the single-input-single-output wiretap channel with single-antenna jammers. Differing from the existing works concerning the secrecy rate maximization, this paper studies the problem of minimizing the secrecy ...
