The evolution of technology and the internet led to the opening of infinite ways to engage with consumers worldwide. The idea of everything taking place online is now applicable for the finance and banking sector as well. The system of online wallets and e-transactions have become very common as a mode of payment. But handling money on a network is also dangerous as hackers may break into the firewall. The security wireless communication in e-commerce has received extensive attention recently. This paper offers an analytical framework to investigate the eavesdropping attacks over wireless communication link. Eavesdropping attack, as one of typical security threats in wireless communication systems, has attracted considerable attention. We will observe the physical layer security of an arbitrarily dimensioned wireless network in the presence of an unauthorized attacker. In this paper, we will explain different models of eavesdropping and attacks. Also, we will consider basic performance of the system such are secrecy outage probability (SOP), strictly positive secrecy capacity (SPSC) and average secrecy capacity (ASC) based on a probability density function (PDF) and specific cumulative distribution function (CDF).

“…The statistical behavior of signals in such systems can be described by different distributions: by Rayleigh, Rician, Nakagami-m, Weibull or κ-μ [2], [6], [7]. κ-μ distribution can be used to describe the variation of the signal envelope in linear environments where it is a dominant component.…”

Channel capacity of the macrodiversity SC system in the presence of kappa-mu fading and correlated slow gamma fading

et al. 2018

In this paper macrodiversity system consisting of two microdiversity SC (Selection Combiner) receivers and one macrodiversity SC receiver are analyzed. Independent κ-μ fading and correlated slow Gamma fading are present at the inputs to the microdiversity SC receivers. For this system model, analytical expression for the probability density of the signal at the output of the macrodiversity receiver SC, and the output capacity of the macrodiversity SC receiver are calculated. The obtained results are graphically presented to show the impact of Rician κ factor, the shading severity of the channel c, the number of clusters µ and correlation coefficient ρ on the probability density of the signal at the output of the macrodiversity system and channel capacity at the output of the macrodiversity system. Based on the obtained results it is possible to analyze the real behavior of the macrodiversity system in the presence of κ-μ fading.
