摘要：Vehicular ad hoc networks (VANETs) are the specific class of Mobile ad hoc networks (MANETs).In a VANET, vehicles will rely on the integrity of received data for deciding when to present alerts to drivers.In this paper, we investigate the authentication issues with privacy preservation and non-repudiation in VANETs. We propose a novel framework with preservationand repudiation (ACPN) for VANETs. In ACPN, we introduce the public-key cryptography (PKC) to the pseudonym generation, which ensures legitimate third parties to achieve the non-repudiation of vehicles by obtaining vehicles' real IDs. The self-generated PKCbasedpseudonyms are also used as identifiers instead of vehicle IDs for the privacy-preserving authentication, while the update of the pseudonyms depends on vehicular demands
