Secrecy outage probability and intercept probability analysis over α-F fading channels

In this paper, we investigated the secrecy performance of traditional Wyner's wiretap model over α-F fading channels. The expressions for evaluating the secrecy outage probability and the probability of intercept are derived. Due to high generality of assumed fading model which includes other models as special or limiting cases, presented analysis is quite general. Based on obtained analytical results, the impact of fading depth and shadowing severity of main/wiretap channel on the physical layer security metrics is studied. The results showed that secrecy transmission can be enhanced by proper exploiting propagation characteristics of authorized/unauthorized wireless channels.
