Joint Antenna and User Selection for Untrusted Relay Networks [PDF]
2018 IEEE Global Communications Conference (GLOBECOM), 2018 In this paper, we investigate secure communication for an untrusted relay network, in which a source equipped with $N_{S}$ antennas communicates to $M$ users with the help of an untrusted relay. To protect the data confidentially while concurrently relying on the untrusted relays, joint antenna and user selection scheme has been proposed with the ...

Dynamic Continuous Variable Quantum Key Distribution for Securing a Future Global Quantum Network
Advanced Quantum Technologies, Volume 8, Issue 10, October 2025.The article explores securing a dynamic global quantum network using continuous variable QKD, proposing a unified three‐layer network architecture for integrating existing QKD networks. It evaluates secret key rates across various channels and introduces the link capacity as a metric for determining the optimum path for secret key distribution in a ...

End-to-End Physical Layer Authentication for Dual-Hop Wireless Networks
IEEE Access, 2019 End-to-end (E2E) physical layer authentication for multi-hop wireless networks is still not well-explored by now. Like one step forward in this direction, this paper focuses on the E2E physical layer authentication in a dual-hop wireless network with an ...

Secrecy Performance of a Multi-NOMA-MIMO System in the UEH Relaying Network Using the PSO Algorithm
IEEE Access, 2021 In this paper, we investigate the secrecy performance of the nonorthogonal multiple access (NOMA) system in an untrusted relaying energy harvesting (UEH) network with the multiple-input multiple-output (MIMO) architecture using the maximum ratio ...

Leveraging Blockchain and Smart Contracts to Combat Greenwashing in Sustainable Development
Sustainable Development, Volume 33, Issue 4, Page 5874-5889, August 2025.ABSTRACT Blockchain technology, when combined with smart contracts, enables buyers to distinguish between greenwashed and genuinely eco‐friendly products. The presence of counterfeit items can severely impact supply chains by diminishing brand value, eroding consumer confidence, and undermining market trust.

Security Energy Efficiency Maximization for Untrusted Relay Assisted NOMA-MEC Network With WPT
IEEE Access, 2020 Relay assisted transmission can effectively improve the range of coverage and offloading efficiency of non-orthogonal multiple access-mobile edge computing (NOMA-MEC) system. However, the relay will become untrusted relay when it is attacked by malicious

International Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...
