BlockChain Based Data Security Mechanism for Vehicular Networks

In vehicular networks, information security is of importance to most if not all applications. In addition, vehicles are naturally tied with location as part of privacy. Thus, we have obtained a distributed network in a vehicular network. The emerging block-chain inspired us to design a decentralized security scheme over vehicular network. In this paper, we propose a block-chain based security mechanism in a vehicular network scenario. Information will be recorded and signed over the blockchain so it greatly enhances the integrity of data. The proposed method evaluated by simulations is efficient and secure.
