Electronic Payment Schemes Based on Blockchain in VANETs

Vehicular ad-hoc networks (VANETs) is considered as an important part of intelligent transportation system (ITS). Depending on the interconnection between vehicles and roadside units (RSUs), VANETs can provide a variety of application services for drivers and passengers. Due to the necessary service cost, many applications have to face the problem of how to charge vehicle for the services. This paper, which relies on blockchain technology, takes park toll management system and electronic toll collection system (ETC) as scenarios. Two payment schemes, V-R transaction and V-Rs transaction, are then proposed. The security and performance analysis show that the proposed schemes are efficient and robust.
