【Abstract】With all the advancements in the last decade in Intelligent Transportation systems (ITS), there has been an exponential increase in the number of applications provided to the Vehicular Ad Hoc Networks (VANETs). These applications provide unmatched security and safety services. As a result, there is a huge surge in the amount of data being generated and transmitted within the VANETs. In this paper, we have proposed a dual blockchain based decentralized architecture for authentication of the vehicles and secure & efficient communication within the network. The use of individual blockchains for authentication and message sharing makes the network more efficient and fast while also helping to increase the network security. Both the blockchains use a different consensus algorithm which adds another layer of security. The security and performance evaluation of the proposed architecture proves that it is resistant to a number of security attacks and has a lower computational cost, higher throughput, lower transmission delay and higher vehicle verification rate by a significant amount when compared to existing schemes.
