Impact of Heterogeneity and Secrecy on theCapacity of Wireless Sensor Networks

open access: yesSensors, 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

Coding for Wireless Broadcast and Network Secrecy [PDF]

open access: yes, 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.

pRate: Anonymous Star Rating with Rating Secrecy

open access: yes, 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

open access: yesIEEE 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

Virtual full-duplex buffer-aided relay selection schemes for secure cooperative wireless networks

open access: yesEURASIP 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.

Secure Massive MIMO Downlink With Low-Resolution ADCs/DACs in the Presence of Active Eavesdropping

open access: yesIEEE Access, 2020
In this paper we study the secrecy performance of a downlink massive multiple-input multiple-output (MIMO) system in the presence of pilot spoofing attack (PSA). Specifically, the base station (BS), which is equipped with low-resolution analog-to-digital
