“…The analytical expressions of SOPM, ESMC, and PNSMC are numerically illustrated in this section in terms of the environmental fading and shadowing conditions with multiple relays, users, and eavesdroppers. Although the final closed form expressions in (46), (57), and (58) contain infinite sums, the values of the expressions converge accurately for first 20 terms. The accuracy of the expressions of the performance metrics mentioned above is validated through Monte-Carlo simulation via MATLAB which shows a perfect match with the analytical results.…”

In this era of 5G technology, the ever-increasing demands for high data rates lead researchers to develop hybrid satellite-terrestrial (HST) networks as a substitution to the conventional cellular terrestrial systems. Since an HST network suffers from a masking effect which can be mitigated by adopting the terrestrial relaying strategy, in this work, wireless multicasting is focused on through an HST relaying network (HSTRN) in which a satellite sends messages to multiple terrestrial nodes via multiple relays under the wiretapping efforts of multiple eavesdroppers. The concern is to protect the multicast messages from being eavesdropped taking advantage of the well-known opportunistic relaying technique. It is considered that the satellite links follow Shadowed Rician fading whereas the terrestrial links undergo 𝛼 − 𝜇 fading. The secrecy performance of the proposed HSTRN model is accomplished by deriving expressions for the probability of nonzero secrecy multicast capacity, ergodic secrecy multicast capacity, and secure outage probability for multicasting in closed-form. Capitalizing on the derived expressions, the authors analyze how a perfect secrecy level can be preserved in spite of harsh channel conditions and also present a secrecy trade-off in terms of the number of relays, multicast users, and multiple eavesdroppers. Finally, the numerical analyses are corroborated via Monte-Carlo simulations.

“…The position of eavesdropper was considered close to the destination in [44], [45] where the authors presented the expressions of SOP and strictly positive secrecy capacity (SPSC) with DF relaying system. A passive RF eavesdropping scheme was used in mixed RF-FSO systems over ΓΓ [46], [47], Málaga [48]- [50], exponentiate-Weibull [42], [51], etc., scenarios to obtain ASC, SOP, and SPSC. The effects of transmit antenna selection (TAS) scheme over the RF hop in a RF-FSO mixed system was examined by [52].…”

This work deals with the secrecy performance analysis of a dual-hop RF-FSO DF relaying network composed of a source, a relay, a destination, and an eavesdropper. We assume the eavesdropper is located close to the destination and overhears the relay's transmitted optical signal. The RF and FSO links undergo (α − κ − µ)-shadowed fading and unified Málaga turbulence with pointing error. The secrecy performance of the mixed system is studied by deriving closed-form analytical expressions of secure outage probability (SOP), strictly positive secrecy capacity (SPSC), and intercept probability (IP). Besides, we also derive the asymptotic SOP, SPSC, and IP upon utilizing the unfolding of Meijer's G function where the electrical SNR of the FSO link tends to infinity. Finally, the Monte-Carlo simulation is performed to corroborate the analytical expressions. Our results illustrate that fading, shadowing, detection techniques (i.e. heterodyne detection (HD) and intensity modulation and direct detection (IM/DD)), atmospheric turbulence, and pointing error significantly affect the secrecy performance. In addition, better performance is obtained exploiting the HD technique at the destination relative to IM/DD technique.INDEX TERMS Intercept probability, Málaga turbulence, physical layer security, secure outage probability.

“…Since the eavesdropper tries to overhear the RF link between the legitimate transmitter and receiver of the hybrid system, secure performance need be analysed. Reference [27] introduced the secrecy measurements by deriving closed-form mathematical formulas of secure metrics such as SOP, ASC and SPSC. Reference [28] derived the exact SOP and the probability of SPSC expressions for two transmit antenna selection (TAS) mechanisms.…”

We study the secrecy transmission of uplink non-orthogonal multiple access (NOMA) with single antenna and multi-antenna users in presence of an eavesdropper. Two phases are required for communications during each time frame between the users and the base station in cellular networks. We study the case where an eavesdropper overhears the relay and direct links from the users to the base stations. In terms of the secure performance analysis, we focus on two main metrics including secrecy outage probability (SOP) and strictly positive secrecy capacity (SPSC) with the assumption that the eavesdropper is able to detect the signals. Analytical closed-form expressions for the SOP and SPSC are derived to evaluate the system secure performance achieved by the proposed schemes. Furthermore, the asymptotic analysis is presented to gain further insights. The analytical and numerical results indicate that the proposed schemes can realize better secrecy performance once we improve the channel condition and signal-to-noise ratio (SNR) at the base station. Our results confirms that the secrecy performance gaps exist among the two users since different power allocation factors are assigned to these users.INDEX TERMS Physical layer security, non-orthogonal multiple access, secrecy outage probability, strictly positive secrecy capacity.
