“…ASC, SOP, and SPSC. As per the authors' knowledge based on the open literature, we are the first to derive the expressions in (20), (24), and (30) corresponding to our proposed model, and hence our derived expressions are totally novel. It is noteworthy to point out that for the special case of Rayleigh-ΓΓ scenario, our derived expressions in (24) reduce to the expressions of [35,Eqs.…”

“…In [29], the presence of an eavesdropper was assumed to be in the relay-destination link, and the authors deduced the closed-form expressions for SOP and strictly positive secrecy capacity (SPSC) employing DF relaying scheme. In [30], a SWIPT scenario was proposed where the energy receiver acts as a potential eavesdropper. The authors investigated the secrecy capability of the proposed RF-FSO cooperative system with multiple antennas at the receiver by deriving the closedform expressions for ASC and SOP.…”

On Secrecy Performance of Mixed Generalized Gamma and Málaga RF-FSO Variable Gain Relaying Channel

The emergence of an array of new wireless networks has led researchers to evaluate the prospect of utilizing the physical properties of the wireless medium in order to design secure systems. In this paper, the physical layer secrecy performance of a mixed radio frequency-free space optical (RF-FSO) system with variable gain relaying scheme is investigated in the presence of an eavesdropper. We assume that the eavesdropper can wiretap the transmitted confidential data from the RF link only. It is further assumed that the main and eavesdropper RF links are modeled as generalized Gamma (GG) fading channel, and the free space optical (FSO) link experiences Málaga turbulence with pointing error impairment. Our primary concern is to protect this confidential information from being wiretapped. Besides pointing error, the atmospheric turbulence and two types of detection techniques (i.e. heterodyne detection and intensity modulation with direct detection) are also taken into consideration. Utilizing amplify-and-forward (AF) scheme, the novel mathematical closed-form expressions for average secrecy capacity, lower bound of secrecy outage probability, and strictly positive secrecy capacity are derived. As both the links (RF and FSO) undergo generalized fading channels, the derived expressions are also general. We present a unification of some existing works utilizing the proposed model to better clarify the novelty of this work. Finally, all the derived expressions are justified via Monte-Carlo simulations. INDEX TERMS Physical layer security, Generalized Gamma fading, Málaga fading, variable gain relay, average secrecy capacity, strictly positive secrecy capacity, and secrecy outage probability.

“…The same channels were used in [39] considering multiuser scenario and in [40] considering a simultaneous wireless information and power transfer (SWIPT) system. A Nakagami-m-Málaga faded SWIPT system was employed in [41]. The authors derived the expressions of ASC and lower bound of SOP to examine the effect of multiple antennas, energy harvesting, pointing error, and detection techniques.…”

Secrecy Performance Analysis of Mixed Hyper-Gamma and Gamma-Gamma Cooperative Relaying System

In this paper, we investigate a secure dual-hop radio frequency-free space optical (RF-FSO) mixed variable gain relaying framework in the presence of a single eavesdropper. The RF and FSO links are modeled with hyper Gamma (HG) and Gamma-Gamma (ΓΓ) fading channels, respectively. We assume that the eavesdropper utilizes another HG fading channel to wiretap the transmitted confidential data from the RF link. Our key concern is to defend this information against passive eavesdropping. We carry out the secrecy measurements by deriving closed-form mathematical expressions of average secrecy capacity (ASC), secure outage probability (SOP), and strictly positive secrecy capacity (SPSC), all in terms of Meijer's G function. Capitalizing on the derived expressions, we analyze the impacts of atmospheric turbulence and pointing errors on the secrecy capacity and outage performance of the proposed scenario. For gaining more insights, we also analyze the asymptotic outage behaviour for high signal-to-noise ratio. Two detection techniques i.e. heterodyne (HD) and the intensity modulation with direct detection (IM/DD) are taken into consideration and our results demonstrate that HD technique notably outperforms the IM/DD scheme. The supremacy and novelty of the model is demonstrated via utilizing generic properties of the HG fading channel. Finally, we provide a justification of the derived expressions via Monte-Carlo simulations. INDEX TERMS Gamma-Gamma fading, eavesdropper, Hyper-Gamma fading, physical layer security, pointing error, variable gain relay.

Similarly, in [17], the author's evaluated the PLS performance for a two‐way relay based mixed RF/FSO network assuming similar channel models as in [16], but ignored the effects of non‐zero boresight. Thereafter, the PLS performance for a mixed RF/FSO system under Gamma–Gamma AT model with PE (only jitter) has been analysed in [18].…”

Free space optical (FSO) communication is a promising candidate for the next generation (5G and beyond) wireless communication systems, due to its merits (i.e. low latency, high data rate, and license-free band, among others). However, atmospheric turbulence (AT) as well as pointing error (PE) are two of the main challenges with FSO communication that affect its performance. Here, the exact closed-form expression of the average secrecy capacity and secrecy outage probability under the composite effect of AT and non-zero boresight PEs is evaluated. For all the regimes of the AT (weak to strong), a generalised Malaga distribution is used to model the channel fading gain of the FSO link. The expressions are generalised and valid for all turbulence, and are applicable for intensity modulation direct detection as well as heterodyne detection techniques.
