“…Information-theoretic security, i.e., physical layer security (PLS), has attracted plenty of attentions [1], since the seminal work was established by Shannon and Wyner. On the basis of the classic Wyner's wiretap channel model, many work related to the secrecy performance analysis over various fading channels, including the Gaussian fading channels [2], Rayleigh [3], Rician [4], [5], Nakagami-m [6], Weibull [7], genralized-K [8], α − µ [9]- [13], κ − µ [14], α-η-κ-µ [15], Fisher-Snedor F [16], and Fox's H-function fading channel [17], etc., were done. Apart from the aforementioned fading model, other models, including the composite fading model and cascaded fading model, are also widely used to characterize some wireless communication scenarios.…”

In this paper, we have investigated the physical layer security over cascaded Fisher-Snedecor F fading channels in the presence of randomly distributed eavesdroppers. To characterize the eavesdroppers' intercept capability, both the conceptual k-th nearest and best eavesdroppers are introduced. The probability density function (PDF) of the k-th nearest and best eavesdropper is characterized. The probability of interception, Pint, is correspondingly regarded as the secrecy metric, and is further derived with closed-form expressions in terms of Fox's H-function. For the purposes of providing more insights, the asymptotic behavior of the intercept probability is also provided. To explore the effects of the eavesdroppers' density and the channel fading conditions on the secrecy performance, we have performed the Monte-Carlo simulation and compared our analytical results with the simulated ones. One can find that our analytical results are successfully verified by the simulation results.

“…The secrecy outage probability is a useful secrecy performance metric for the scenario of passive eavesdropping, where node S does not have CSI on the eavesdropper's channel [6]. The secrecy outage probability is defined as the probability that the instantaneous secrecy capacity is below a predefined threshold rate R s [33], i.e.,…”

In this paper, we study the physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system. The satellite links are assumed to follow the shadowed-Rician fading distribution, and the channel of the terrestrial link between the relay and destination is assumed to experience the gamma-gamma fading. For the FSO communications, the effects of different types of detection techniques (i.e., heterodyne detection and intensity modulation with direct detection) as well as the pointing error are considered. We derive exact analytical expressions for the average secrecy capacity and secrecy outage probability (SOP) for both cases of amplify-and-forward (AF) and decodeand-forward (DF) relaying. The asymptotic analysis for the SOP is also conducted to provide more insights on the impact of FSO and satellite channels on secrecy performance. It is found that with the AF with fixed gain scheme, the secrecy diversity order of the investigated system is only dependent on the channel characteristics of the FSO link and the FSO detection type, whereas the secrecy diversity is zero when the relay node employs DF or AF with variable-gain schemes.

“…The absence of secret keys makes it outperform the conventional cryptography technique from the information-theoretic viewpoint. In recent decades, plenty of works have studied the PLS over various fading channels, e.g., Rayleigh [1], Rician (Nakagami-n) [2], Hoyt (Nakagami-q) [3], α − µ [4]- [6], cascaded α − µ [7], κ − µ [8], Lognormal [9], Fisher-Snedecor F [10], generalized-K [11], extended generalized-K (EGK) [12], α − η − κ − µ [13], Málaga [14], etc.…”

The mixture of Gaussian (MoG) distribution was proposed to model the wireless channels by implementing the completely unsupervised expectation-maximization (EM) learning algorithm. With the high convenience for density estimation applications, the focus of this letter is supposed to investigate the secrecy metrics, including secrecy outage probability (SOP), the lower bound of SOP, the probability of non-zero secrecy capacity (PNZ), and the average secrecy capacity (ASC) from the information-theoretic perspective. The above-mentioned metrics are derived with simple and unified closed-form expressions. The effectiveness of our obtained analytical expressions are successfully examined and compared with Monte-Carlo simulations. One can conclude that this letter provides a simple but effective closedform secrecy analysis solution exploiting the MoG distribution.
