“…We can see that the SOP performance of the considered system under Scenario I performs better than the other two schemes as MER goes up. Under Scenario II , the SOP performance of the proposed scheme is better than the direct transmission‐only scheme; however, it is poorer than in the work of Zhang and Pan because of the bottleneck MER of the direct link.…”

“…This is owing to the relatively better diversity gain of the considered system. We also plot the SOP performance of DF relay scheme for fair comparison, where the direct S → D and S → E links are not considered. It can be observed from Figure that the SOP performance of the considered system outperforms the one presented in the work of Zhang and Pan in the medium‐to‐high MER regime.…”

“…Sun et al have analyzed the secrecy performance for the AF‐based V2I networks with a fixed eavesdropper terminal under Rayleigh channels. Zhang and Pan have evaluated the secrecy performance for a DF‐based V2V network over double‐Rayleigh fading channels. However, in the aforementioned works, the authors did not exploit the direct links between the source and destination and between the source and the eavesdropper.…”

“…Zhang and Pan have evaluated the secrecy performance for a DF‐based V2V network over double‐Rayleigh fading channels. However, in the aforementioned works, the authors did not exploit the direct links between the source and destination and between the source and the eavesdropper. Therefore, to the best of authors' knowledge, the PHY‐security for cooperative vehicular networks by using AF protocol at the relay terminal and exploiting the direct links between the source and destination terminals and between the source and eavesdropper terminals has not been investigated in the open literature.…”

In this paper, we address the physical layer security of a cooperative vehicular network in the presence of a passive eavesdropper vehicle, where the communication from a fixed source node to a fixed destination node is assisted by an amplify‐and‐forward relay vehicle and by direct link, in two transmission phases. Based on the security of the first transmission phase, we consider two scenarios for the cooperative vehicular networks. In Scenario I, the first phase is secure (ie, the direct link between source and eavesdropper is not available) and the eavesdropping occurs only in the second phase. In Scenario II, the first phase is not secure (ie, the direct link between source and eavesdropper is present) and the eavesdropping occurs during both the first and second phases. We assume that source‐to‐destination, source‐to‐relay vehicle, relay vehicle‐to‐destination, and source‐to‐eavesdropper vehicle channels are modeled as Rayleigh fading, whereas the channel between relay and eavesdropper vehicles is modeled by double‐Rayleigh fading. Under such channel modeling, we deduce the new tight closed‐form expressions for the secrecy outage probability (SOP) under both Scenario I and Scenario II. We also investigate the effective secrecy diversity order in the high main‐to‐eavesdropper ratio (MER) regime. The numerical and simulation results corroborate our theoretical analysis and findings and show the occurrence condition for SOP floor phenomenon and influences of channel conditions and relay and eavesdropper locations on the SOP performance. Our results also reveal that the presence of source‐to‐eavesdropper link has significant impact on the SOP performance and relay location.
