Secrecy Rate of Two-Hop AF Relaying Networks with an Untrusted Relay

Wireless Personal Communications, 2013
Two cooperative communication protocols, two-way and one-way half-duplex relayings, are investigated and then compared in the amplify-and-forward (AF) mode. The relay is assumed to play the roles of eavesdropper and relay (i.e., an untrusted relay). With a fair power constraint at each node, the secrecy rate of the one-way relaying protocol is proved ...

Securing Task Computation Offloading for Mobile Edge Computing in Untrusted Relay Networks

International Conference on Telecommunications
This paper aims to secure task offloading and service caching in relay-assisted heterogeneous mobile edge computing networks. The relay nodes might be untrusted in such heterogeneous networks due to their limited computational power.

Cooperation with an untrusted relay in broadcast channels

2013 IEEE International Symposium on Information Theory, 2013
This paper studies secure communication over the broadcast channels with an untrusted relay. The relay helps users with transmission in broadcast channels, but we also wish to keep the information secret against the relay. Compress-and-forward relaying is a potential strategy to achieve secrecy.

Performance of Untrusted Amplify-and-Forward Relaying

2013 4th International Conference on Intelligent Systems, Modelling and Simulation, 2013
In this paper, we analyze the secrecy outage performance of amplify-and-forward (AF)-based relay networks consisting of a source, a destination, and an untrusted relay, where each terminal has a single antenna and operates in a half-duplex mode. In this network, the common message is transmitted through the relay-path, and the private message is ...

Machine Learning-Based Adaptive Physical-Layer Security in Untrusted Relay Networks

2025 8th International Conference on Information Communication and Signal Processing (ICICSP)

Physical-layer secret key generation with untrusted relays

2014 IEEE Globecom Workshops (GC Wkshps), 2014
In this paper, we propose a physical-layer secret key generation scheme for multi-antenna legitimate nodes with the help from multiple untrusted relays with single antenna. The relays' actions conform to the rules but they passively eavesdrop the information.

DNN-Based Receive Antenna Selection for PSM-MIMO Systems With Untrusted Relay

International Conference on Signal Processing Systems
In this paper, we propose a novel multiple antenna transmission scheme, which combines the precoded spatial modulation (PSM)-aided multiple-input multiple-output (MIMO) and untrusted relay (UR), in order to joint improve the transit rate and the security,

Power Allocation Strategy of Untrusted Relay Network Based on Stackelberg Game

IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2021
In wireless communication systems, relay can improve the communication quality and increase communication distance. However, most of the current researches treat the relay node as a selfless node, and seldom pay attention to the individual needs and ...

Secure OFDM transmission in wireless networks with untrusted relays

2017 9th International Conference on Wireless Communications and Signal Processing (WCSP), 2017
Physical layer security is becoming a promising technology to face the security challenges of diversified and rapidly-growing wireless applications. In this paper, we propose a three-hop secure Orthogonal Frequency Division Multiplexing (OFDM) transmission protocol for the wireless networks with untrusted relays.
