The Secured Authentication in VANET Through Public Key Cryptography

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 publickey 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. Performance assessment has been done utilizing IBS and IBOOS schemes. We demonstrate that the proposed ACPN is practical and sufficient to be utilized productively as a part of the VANET environment.
