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

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 ...

IEEE Access, 2019 In this paper, we investigate two user scheduling algorithms (optimal user and threshold-based user scheduling algorithms) when we consider potential eavesdroppers in an uplink wiretap network. The optimal user scheduling (OUS) algorithm selects the user

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,

Impact of Heterogeneity and Secrecy on theCapacity of Wireless Sensor Networks
Sensors, 2015 This paper investigates the achievable secrecy throughput of an inhomogeneous wireless sensor network. We consider the impact of topology heterogeneity and the secrecy constraint on the throughput. For the topology heterogeneity, by virtue of percolation

pRate: Anonymous Star Rating with Rating Secrecy
, 2019 We introduce pRate, a novel reputation management scheme with strong security and privacy guarantees for the users and their reputation scores. The reputation scores are computed based on the (aggregated) number(s) of stars that users receive from their raters.

Performance Analysis of Secret Precoding-Aided Spatial Modulation With Finite-Alphabet Signaling
IEEE Access, 2018 The precoding-aided spatial modulation (PSM) is first characterized with respect to its secrecy performance, which shows that the PSM is a secrecy embedded communication scheme when operated in the time-division duplex mode, but experiences security risk
