Abstract: VANET interconnects the vehicles for transferring secure information. In ACPN, the public-key cryptography (PKC) for pseudonym generation is used, which ensures legitimate third parties to achieve the non-repudiation of vehicles by obtaining vehicles' real IDs for privacy preserving authentication and pseudonyms updates on vehicular demands. The convergence point access (CPA) is used to enable communication for out of range vehicles, handover scheme occurs. The scheme provides a seamless connectivity and secure message transmission. However, adversarial nodes could provide false position information. Thus, in VANETs, there is no secure discovery protocol for neighbour positions. We address this problem by designing a distributed protocol that relies on information exchange among one-hop neighbours, we analyse security properties of independent or colluding adversaries, and evaluate its performance using realistic mobility traces. This protocol can be highly effective in detecting falsified position information, while maintaining a low rate of false positive detections.
