Intelligent Reflecting Surface Assisted Secret Key Generation Under Spatially Correlated Channels in Quasi-Static Environments
Vahid Shahiri, Hamid Behroozi, Ali Kuhestani
Physical layer key generation (PLKG) can significantly enhance the security of classic encryption schemes by enabling them to change their secret keys significantly faster and more…
Joint Information Theoretic Secrecy and Covert Communication in the Presence of an Untrusted User and Warden
Moslem Forouzesh, Paeiz Azmi, Ali Kuhestani +1
In this paper, we investigate joint information theoretic secrecy and covert communication in a single-input multi-output (SIMO) system where a transmitter (Alice) is communicating…
Can a Multi-Hop Link Relying on Untrusted Amplify-and-Forward Relays Render Security?
Milad Tatar Mamaghani, Ali Kuhestani, Hamid Behroozi
Cooperative relaying is utilized as an efficient method for data communication in wireless sensor networks and the Internet of Things (IoT). However, sometimes due to the necessity…
Covert Transmission with Antenna Selection and Using an External Jammer
Morteza Sarkheil, Paeiz Azmi, Moslem Forouzesh +1
This paper adopts the antenna selection technique to enhance the covert rate in a wireless communication network comprised of a source, a destination , an external jammer and an ea…
Secure transmission with covert requirement in untrusted relaying networks
Moslem Forouzesh, Paeiz Azmi, Ali Kuhestani
In this paper, we study the problem of secure transmission with covert requirement in untrusted relaying networks. Our considered system model consists of one source, one destinati…
Joint Relay Selection and Power Allocation in Large-Scale MIMO Systems with Untrusted Relays and Passive Eavesdroppers
Ali Kuhestani, Abbas Mohammadi, Mohammadali Mohammadi
In this paper, a joint relay selection and power allocation (JRP) scheme is proposed to enhance the physical layer security of a cooperative network, where a multiple antennas sour…
Optimal Power Allocation by Imperfect Hardware Analysis in Untrusted Relaying Networks
Ali Kuhestani, Abbas Mohammadi, Kai-Kit Wong +3
By taking a variety of realistic hardware imperfections into consideration, we propose an optimal power allocation (OPA) strategy to maximize the instantaneous secrecy rate of a co…
Optimal Power Allocation and Secrecy Sum Rate in Two-Way Untrusted Relaying
Ali Kuhestani, Phee Lep Yeoh, Abbas Mohammadi
In this paper, we examine the secrecy performance of two-way relaying between a multiple antenna base station (BS) and a single antenna mobile user (MU) in the presence of a multip…
Secure two-way communication via a wireless powered untrusted relay and friendly jammer
Milad Tatar Mamaghani, Abbas Mohammadi, Phee Lep Yeoh +1
In this paper, we propose a self-dependent two-way secure communication where two sources exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) r…
Secure Two-Way Transmission via Wireless-Powered Untrusted Relay and External Jammer
Milad Tatar Mamaghani, Ali Kuhestani, Kai-Kit Wong
In this paper, we propose a two-way secure communication scheme where two transceivers exchange confidential messages via a wireless powered untrusted amplify-and-forward (AF) rela…
