On the Secrecy Performance and Power Allocation in Relaying Networks With Untrusted Relay in the Partial Secrecy Regime [PDF]

open access: yesIEEE Transactions on Information Forensics and Security, 2020
Recently, three useful secrecy metrics based on the partial secrecy regime were proposed to analyze secure transmissions on wireless systems over quasi-static fading channels, namely: generalized secrecy outage probability, average fractional equivocation, and average information leakage.

Secrecy performance for multiple untrusted relay networks using destination-based jamming with direct link [PDF]

open access: yes, 2018
We propose a destination-based jamming scheme for cooperative networks with multiple untrusted amplify-and-forward relays, in which the destination operates in full-duplex mode so as to enable simultaneous reception of the information coming directly ...

Subcarrier‐pair based joint resource allocation for secure cooperative OFDM system with multiple untrusted AF relays

open access: yesIET Communications, 2022
In this paper, a cooperative orthogonal frequency division multiplexing system with multiple untrusted amplify‐and‐forward relays is considered. Since there exists no direct link between source and user because of the shadowing effect, a positive system ...

Successive relaying secure transmission scheme based on inter-relay interference cancellation

open access: yesTongxin xuebao, 2017
A secure scheme based on inter-relay interference cancellation was proposed to solve untrusted relay eavesdropping problem in successive relaying systems.First inter-relay interference between trusted relay and untrusted relay was exploited as artificial

Cooperative Covert Communication With Transceiver Hardware Impairments

open access: yesIEEE Open Journal of the Communications Society
This study investigates covert communication in the presence of a half-duplex amplify-and-forward (AF) relay, while accounting for transceiver hardware impairments. A cooperative jamming strategy and channel uncertainty are employed to achieve covertness.

A novel secure relay selection strategy for energy-harvesting-enabled Internet of things

open access: yesEURASIP Journal on Wireless Communications and Networking, 2018
In this article, we focus on the problem of relay selection for the cooperative cognitive radio-based Internet of things. In such systems, a pair of primary user devices (PUs) can only communicate with each other through a relay.

Secrecy rate optimization for SWIPT in two‐way relay networks with multiple untrusted relays and channel estimation errors

open access: yesIET Communications, 2021
The secrecy rate of two‐way untrusted relay networks with imperfect channel state information based on SWIPT is investigated when multiple relays harvest energy from two sources.

Noiseless Linear Amplifiers in Entanglement-Based Continuous-Variable Quantum Key Distribution

open access: yesEntropy, 2015
We propose a method to improve the performance of two entanglement-based continuous-variable quantum key distribution protocols using noiseless linear amplifiers. The two entanglement-based schemes consist of an entanglement distribution protocol with an
