Coding for Wireless Broadcast and Network Secrecy [PDF]
, 2010 In the first part of this thesis, we exploit wireless broadcast across different layers in wireless networks. The wireless channel is distinguished by its broadcast nature.

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.

Virtual full-duplex buffer-aided relay selection schemes for secure cooperative wireless networks
EURASIP Journal on Wireless Communications and Networking, 2022 This paper considers secure communication in buffer-aided cooperative wireless networks in the presence of one eavesdropper, which can intercept the data transmission from both the source and relay nodes.

Secrecy rate maximization in multi-IRS mmWave networks [PDF]
Physical Communication, 2021 Abstract This paper investigates the problem of improving security at the physical layer of a Millimeter Wave (mmWave) network equipped with multiple Intelligent Reflecting Surfaces (IRSs). In this network, the IRSs help the Base Station (BS) in transmitting its signal to the desired user and at the same time improving the physical layer security of ...

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
