Secure Transmission of Terahertz Signals with Multiple Eavesdroppers

open access: yesMicromachines, 2022
The terahertz (THz) band is expected to become a key technology to meet the ever-increasing traffic demand for future 6G wireless communications, and a lot of efforts have been paid to develop its capacity.

Artificial Noise Aided Secure Transmission for Active RIS-Aided NOMA Networks

open access: yesIEEE Access, 2023
A secrecy rate maximization problem for active reconfigurable intelligent surface (RIS) aided non-orthogonal multiple access networks has been studied in this paper. Assuming that the perfect channel state information is available, we aim to maximize the

Noise Optimization for Artificial Neural Networks

open access: yesCoRR, 2021
Se ha demostrado que la adición de ruidos a la red neuronal artificial (ANN) puede mejorar la solidez en trabajos anteriores. En este trabajo, proponemos una nueva técnica para calcular la estimación del gradiente estocástico Pathwise con respecto a la desviación estándar del ruido gaussiano añadido a cada neurona de la ANN.

Noise-induced artificial intelligence

open access: yesPhysical Review Research, 2022
We show that unavoidable stochastic fluctuations are not only affecting information processing in a destructive or constructive way, but may even induce conditions necessary for the artificial intelligence itself. In this proof-of-principle paper we consider a model of a neuron-astrocyte network under the influence of multiplicative noise and show that

Ergodic Secrecy Rate Analysis and Optimal Power Allocation for Symbiotic Radio Networks

open access: yesIEEE Access, 2023
In this paper, we address the challenge of establishing secure communication within a symbiotic radio (SR) network. This network comprises a primary transmitter (PT), a primary receiver (PR), a passive backscatter device (BD), and an eavesdropper (ED ...

Two Low-Complexity Efficient Beamformers for an IRS- and UAV-Aided Directional Modulation Network

open access: yesDrones, 2023
As excellent tools for aiding communication, an intelligent reflecting surface (IRS) and an unmanned aerial vehicle (UAV) can extend the coverage area, remove the blind area, and achieve a dramatic rate improvement.

Reliability and Security Performance Analysis of Hybrid Satellite-Terrestrial Multi-Relay Systems With Artificial Noise

open access: yesIEEE Access, 2021
Land mobile satellite communication and physical layer security are considered as the promising paradigms in beyond 5G networks. In this paper, we establish the multi-relay hybrid satellite-terrestrial systems (HSTSs) with artificial noise (AN) to ...

Secure MISO-NOMA Transmission With Artificial Noise [PDF]

open access: yesIEEE Transactions on Vehicular Technology, 2018
This correspondence studies a new secrecy beamforming (SBF) scheme for multiple-input single-output non-orthogonal multiple access (MISO-NOMA) systems. In particular, the proposed SBF scheme efficiently exploits artificial noise to protect the confidential information of two NOMA assisted legitimate users, such that only the eavesdropper's channel is ...

Improving Secrecy for Correlated Main and Wiretap Channels Using Cooperative Jamming

open access: yesIEEE Access, 2019
To reduce the secrecy loss due to the correlation between main and wiretap channels, this paper introduces a cooperative jamming relay to degrade the reception at the eavesdropper.
