Secrecy Rate Optimizations for MIMO Communication Radar [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2018 In this paper, we investigate transmit beampattern optimization techniques for a multiple-input multiple-output radar in the presence of a legitimate communications receiver and an eavesdropping target. The primary objectives of the radar are to satisfy a certain target-detection criterion and to simultaneously communicate safely with a legitimate ...

Evolutionary Game-Based Secrecy Rate Adaptation in Wireless Sensor Networks
International Journal of Distributed Sensor Networks, 2015 Physical layer security, whose aim is to maximize the secrecy rate of a source while keeping eavesdroppers ignorant of data transmitted, is extremely suitable for Wireless Sensor Networks (WSNs). We therefore, by developing the classical wire-tap channel,

Secrecy & Rate Adaptation for secure HARQ protocols [PDF]
2013 IEEE Information Theory Workshop (ITW), 2013 This paper is dedicated to the study of HARQ protocols under a secrecy constraint. An encoder sends information to a legitimate decoder while keeping it secret from the eavesdrop-per. Our objective is to provide a coding scheme that satisfies both reliability and confidentiality conditions.

Feasibility of positive secrecy rate in wiretap interference channels [PDF]
2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014 Interference usually is an adverse phenomenon in wireless networks. However, the interference can potentially be used to boost the secrecy rate in wireless interference channels. This work studies the secrecy rate in a two-user interference network where unintended user may overhear one of the users, namely user 1.

On Secrecy Outage Probability and Average Secrecy Rate of Large‐Scale Cellular Networks
Wireless Communications and Mobile Computing, 2018 We investigate the secrecy performance in large‐scale cellular networks, where both Base Stations (BSs) and eavesdroppers follow independent and different homogeneous Poisson point processes (PPPs). Based on the distances between the BS and user, the intended user selects the nearest BS as serving BS to transmit the confidential information.

Achievable Secrecy Rates of an Energy Harvesting Device [PDF]
IEEE Journal on Selected Areas in Communications, 2016 The secrecy rate represents the amount of information per unit time that can be securely sent on a communication link. In this work, we investigate the achievable secrecy rates in an energy harvesting communication system composed of a transmitter, a receiver and a malicious eavesdropper. In particular, because of the energy constraints and the channel

On the secrecy rate region for the interference channel
2008 IEEE 19th International Symposium on Personal, Indoor and Mobile Radio Communications, 2008 This paper studies interference channels with security constraints. The existence of an external eavesdropper in a two-user interference channel is assumed, where the network users would like to secure their messages from the external eavesdropper. The cooperative binning and channel prefixing scheme is proposed for this system model which allows users
