Covertness and secrecy study in untrusted relay-assisted D2D networks
This article investigates the covertness and secrecy of wireless communications in an untrusted relay-assisted device-to-device (D2D) network consisting of a full-duplex base station (BS), a user equipment (UE), and an untrusted relay \(R\).

Secrecy Performance of a Multi-NOMA-MIMO System in the UEH Relaying Network Using the PSO Algorithm
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 ...

Dual IRS‐Assisted Secure Communication for Untrusted Two‐Way AF Relay Network
To address the performance loss caused by the difficulty of balancing phase configuration requirements in single‐IRS‐assisted asymmetric bidirectional secure relay communication, this paper proposes a dual‐IRS collaborative optimization framework. Specifically, each user is configured with a dedicated IRS to enable personalized signal reflection, and ...

Device‐Independent Quantum Key Distribution: Protocols, Quantum Games and Security
Device‐independent quantum key distribution (DIQKD) removes the need to trust internal device behaviour by certifying security through Bell‐inequality violations, thereby closing practical loopholes in conventional QKD. This paper systematically reviews DIQKD foundations (Bell tests and security definitions), protocol frameworks (CHSH‐based and ...

Secure communications with untrusted relays: a multi‐pair two‐way relaying approach
Physical‐layer security is usually ensured by the injection of artificial noise (AN) at the legitimate source or destination when relays are cooperative but untrusted. In this work, in order to avoid the power‐consuming AN at the legitimate user pairs, the authors investigate multi‐pair two‐way relaying as a solution for secure transmission in wireless

Exploiting privacy‐aware user task offloading in a multi‐UAV–assisted edge computing system offers a new approach to reduce and balance energy consumption and latency. However, the complexity and variability of operating scenarios can make privacy‐aware user task offloading strategies challenging. This paper examines a system with multiple ground users,
