Abstract
These days, Internet of Things (IoT) is widely used in several real-life applications viz., smart agriculture, smart city, smart healthcare, and smart vehicles. Smart vehicles are interconnected and deliver a variety of sophisticated services to their owners, transit authorities, automobile manufacturers, and other service providers. Smart cars could be exposed to a number of security and privacy risks, including Global Positioning System (GPS) tracking and remote vehicle hijacking. In vehicular IoT, a variety of data are stored in cloud and any alteration in data can cause major road accidents. Blockchain is an evolving technology that can be used for security using decentralization and smart contracts. It is a viable solution for implementing security in vehicular IoTs. In this paper, we presented a blockchain-based methodology to preserve users' privacy while simultaneously boosting vehicle security. The proposed methodology keeps the vehicle data at the servers and related hash values are stored in the blockchain. Thus, the proposed model offers security using decentralization of data. This method outperforms the existing methods in terms of security as well as efficiency.
