On Security and Throughput for Energy Harvesting Untrusted Relays in IoT Systems Using NOMA
IEEE Access, 2019 In this paper, we analyze the secrecy and throughput of multiple-input single-output (MISO) energy harvesting (EH) Internet of Things (IoT) systems, in which a multi-antenna base station (BS) transmits signals to IoT devices (IoTDs) with the help of ...

Device‐Independent Quantum Key Distribution: Protocols, Quantum Games and Security
IET Quantum Communication, Volume 7, Issue 1, January/December 2026.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 ...

Weak Secrecy in the Multiway Untrusted Relay Channel With Compute-and-Forward [PDF]
IEEE Transactions on Information Forensics and Security, 2015 We investigate the problem of secure communications in a Gaussian multi-way relay channel applying the compute-and-forward scheme using nested lattice codes. All nodes employ half-duplex operation and can exchange confidential messages only via an untrusted relay. The relay is assumed to be honest but curious, i.e., an eavesdropper that conforms to the

International Journal of Distributed Sensor Networks, Volume 2026, Issue 1, 2026.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,

Software: Practice and Experience, Volume 55, Issue 11, Page 1749-1772, November 2025.ABSTRACT Introduction The popularization of blockchain‐based applications made evident a critical challenge, namely the inherent isolation of these decentralized systems, akin to the disconnected and technologically diverse local area networks of the 1970s. This lack of interoperability limits the potential for widespread adoption and innovation in the
