In vehicle-to-everything (V2X) communications, collecting sensing data from nearby entities is common and essential. However, this approach also raises grave concerns about the truthfulness of data reported by the senders, particularly the unreliable stakeholders. For example, a compromised vehicle may deliberately disseminate its false location to the surrounding receivers. Trusting the data, a receiver can be trapped to change a wrong lane or accelerate unexpectedly. Such problems can potentially lead to a crash. This letter introduces a novel method by exploiting valuable information from the received physical signals of the multi-array beamforming antennas equipped in V2X-supported vehicles to verify the truthfulness of the claimed GPS location in V2X messages without requiring the availability of many dedicated anchors as in conventional approaches. Simulation results demonstrate that our method is effective and significantly helps to prevent the location forgery attacks in V2X.
