TL;DR: The physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system is studied and 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 theFSO detection type, whereas the secrecy Diversity is zero when the relay node employs DF or AF with variable-gain schemes.

TL;DR: The obtained results reveal the importance of taking the eavesdropper location uncertainty into consideration while designing V2V communication systems.

TL;DR: This paper analyzes the secrecy outage performance of RIS-aided vehicular communications and demonstrates the potential of improving secrecy with the aid of RIS under both V2V and V2I communications.

TL;DR: The results show that when the eavesdropper is placed near the transmitter, atmospheric condition imposes a less significant impact on secrecy performance; certain level of correlation can potentially enhance the secrecy performance for FSO communications; and the correlation imposes opposite impacts on the ASC and SOP of FSOcommunications.

TL;DR: In this paper, the secrecy performance of the classic Wyner's wiretap model, where the main and eavesdropper channels are modeled by a general and versatile $\alpha $ - $\eta$ - $\kappa $ - ''mu $ fading model'' was analyzed.
