Abstract: Malicious attacks on vehicular ad hoc networks (VANET) can cause serious harm, including vehicle accidents. This paper suggests a secure protocol for the authentication of vehicles with roadside units (RSU) in VANET and secure protocols for the online registration of vehicles and RSU with the transport authority (TA). A strategy is also presented for preserving vehicle and traveller privacy during communications with the TA and RSU. The proposed protocol prevents attacks like replay, impersonation, and man-in-the-middle attacks. Lightweight components like XOR and hash functions are used for the authentication of vehicles with the RSU, which makes the protocol faster than the existing protocols. Automated validation of internet security protocols and applications (AVISPA) is used to verify the proposed protocol. The proposed protocol is compared with well-known current approaches, and it is found that the technique used in the proposed protocol overcomes other existing protocols.
