“…The work in [24] inspected secrecy metrics for a dual-hop DF-based multiuser network, under the presence of various eavesdroppers overhearing the second hop. Importantly, the authors of [15], [17], [26], [28], [29], [31], and [33] analyzed the end-to-end PLS of mixed radio-frequency (RF)-optical wireless communication (OWC) systems, where the optical link operates either in indoor (i.e., visible light communications), outdoor (i.e., free-space optics), or in the marine medium (i.e., underwater OWC).…”

“…The authors in [50] analyzed the secrecy performance of a dual-hop hybridterrestrial satellite (HTS) system with an optical feeder, subject to the presence of an eavesdropper per each hop. Lastly, a similar setup was analyzed in [33] by considering an RF-FSO HTS system. Nevertheless, the analysis in all these abovementioned work, ( [31], [33], [48]- [50]), was restricted to a single-antenna assumption in some of or all the nodes along with assuming static nodes with perfect CSI estimation.…”

“…Moreover, all the channels are assumed to follow a Nakagami-m fading model 2 . Hence, this work differs from [25], [32], [37]- [47] by considering independent eavesdroppers per each of the two hops, and from [31], [33], [48]- [50] by taking into account the distortions due to mobility and CSI imperfect estimation. To the best of our knowledge, our work is the first that takes into consideration the joint effect of transceivers mobility and CSI estimation errors, independent eavesdropping per each of the two hops, Nakagami-m fading model, and multi-antenna nodes.…”

In this paper, the physical layer security of a dualhop unmanned aerial vehicle-based wireless network, subject to imperfect channel state information (CSI) and mobility effects, is analyzed. Specifically, a source node (S) communicates with a destination node (D) through a decode-and-forward relay (R), in the presence of two wiretappers (E1, E2) independently trying to compromise the two hops. Furthermore, the transmit nodes (S, R) have a single transmit antenna, while the receivers (R, D, E1, E2) are equipped with multiple receive antennas. Based on the per-hop signal-to-noise ratios (SNRs) and correlated secrecy capacities' statistics, a closed-form expression for the secrecy intercept probability (IP) metric is derived, in terms of key system parameters. Additionally, asymptotic expressions are revealed for two scenarios, namely (i) mobile nodes with imperfect CSI and (ii) static nodes with perfect CSI. The results show that a zero secrecy diversity order is manifested for the first scenario, due to the presence of a ceiling value of the average SNR, while the IP drops linearly at high average SNR in the second one, where the achievable diversity order depends on the fading parameters and number of antennas of the legitimate links/nodes. Furthermore, for static nodes, the system can be castigated by a 15 dB secrecy loss at IP= 3×10 −3 , when the CSI imperfection power raises from 0 to 10 −3 . Lastly, the higher the legitimate nodes' speed, carrier frequency, delay, and/or relay's decoding threshold SNR, the worse is the system's secrecy. Monte Carlo simulations endorse the derived analytical results.

“…The authors designed the UAV trajectory to avoid jamming signals, where the UAV performed reconnaissance tasks and transferred the collected data to the satellite. The work in [31] investigated physical layer security in cognitive satellite-terrestrial networks with jamming, where dual-hop communications were considered under RF and optical links in the first and second hop, respectively. The authors in [32] investigated the closed-form expressions of the secrecy channel capacity and OP for a single relay and perfect CSI.…”

This work investigates the security and reliability analysis for a novel satellite-terrestrial (SatTer) network. Specifically, a satellite attempts to transmit confidential information to a ground user (GU) via the support of multiple relay nodes in the presence of an eavesdropper that tries to overhear the information. A friendly jammer is deployed to improve the secure transmission between the satellite and the relays. Furthermore, satellite-to-relay generalized Rician fading channels and imperfect channel state information (CSI) are deployed to examine a general system model. In this context, the closed-formed expressions for the outage probability (OP) and intercept probability (IP) are derived corresponding to an amplify-and-forward (AF)-based relaying scheme, which is challenging and has not been studied before. Finally, the exactness of the mathematical analyses is validated through Monte Carlo simulations. Furthermore, the effects of various key parameters (e.g., channel estimation errors, satellite's transmit power, relay's transmit power, number of relays, and fading severity parameter) are examined.Index Terms-Cooperative relay, imperfect CSI, physical layer security, satellite communications, shadowed Rician channel I.
