Secure and Trusted Ramp Merging Using Blockchain

Connected vehicles offer a range of sophisticated services that benefit the vehicle owners, manufacturers, transportation authorities, and other mobility service providers. These services are based on underlying communication framework that enables vehicles, roads and other infrastructure, and smart phones to communicate and share vital transportation information through advanced wireless communication technologies. Furthermore, vehicles on the road will likely be using wireless technology, global positioning systems (GPS) and other sensors to attain 360-degree awareness of nearby vehicles. This equipment will continually transmit position, direction, and speed, as well as other information, to other surrounding vehicles. With this great opportunity, connected vehicles can be exposed to a range of security and privacy threats such as location tracking or remote hijacking. In this paper, the authors use blockchain which is a disruptive technology that has been used in many applications from cryptocurrencies to smart contracts, as a potential solution to these challenges. The blockchain technology has the potential to revolutionize connected vehicles. It is far more secure than other record keeping systems because each new message transaction is encrypted and linked to the previous transaction. Blockchain is impossible to be altered once formed. This immutable nature makes it safe from falsified information and hacks. Therefore, the authors propose a blockchain-based scheme to protect the vehicular ecosystem and increase its security. The authors present also an algorithm that uses blockchain to maintain trusted communication between vehicles and test it in a ramp merging application.
