Abstract: Vehicular adhoc networks (VANETs) are an interesting area of exploration among the intelligent transportation research community. Communication among vehicles with infrastructure units is an essential component. Thus, trust and privacy are important concerns in addition to dynamic topology, which is the main characteristic of VANETs. Ensuring the vehicles do not broadcast false information as well as protecting the identity of vehicles against tracking attacks are the objectives of this article. Here, a blockchain-based solution has been proposed to establish an identity-preserving trust model for VANETs. It preserves the real identities of vehicles with the utilization of Ethereum blockchain technology. A trust evaluation algorithm has been implemented to stop the dissemination of fraudulent messages. Validation of the algorithm has been conducted by running the algorithm in different VANET scenarios.

Key words: VANETs, blockchain, identity preservation, trust evaluation
