Abstract
The imminent pervasive adoption of vehicular communication, either localized (ETSI ITS G5, IEEE WAVE or cellular D2D), long range (5G) or hybrid, will foster a richer service ecosystem for vehicular applications. The appearance of new cryptography-based solutions envisaging digital identity and currency exchange are set to stem new approaches for existing and future challenges. This article presents a novel tolling architecture that harnesses the availability of 5G C-V2X connectivity for open road tolling using smartphones, IOTA as the digital currency, and Hyperledger Indy for identity validation. An experimental feasibility analysis is used to validate the proposed architecture for secure, private, and convenient electronic toll payment.
Highlights
Recent advances in wireless communications and crypto technologies are fostering the emergence of innovative solutions for cooperative connected and automated mobility (CCAM)
The tolling server acts as a trusted party and a point-to-point communication is established between the RoadSide Unit (RSU) of the infrastructure and the On Board Unit (OBU) embedded in the vehicle in order to enable the tolling transaction
It is possible to use European Telecommunication Standardization Institute (ETSI) ITS G5 or IEEE WAVE communications to convey the tolling transactions between vehicles and the road side infrastructure, the crypto tolling architecture proposed in this paper considers the use of CV2X communications [8], mainly to allow the use of smartphones instead of specialized devices installed in the vehicles, a change that brings several advantages and key benefits for both users and road operators
Summary
Recent advances in wireless communications and crypto technologies are fostering the emergence of innovative solutions for cooperative connected and automated mobility (CCAM). Another example is the work presented in [3], which investigates how to secure the tolling transactions performed with standard Cooperative Intelligent Transportation System (CITS) equipments. The standardized architecture of the Electronic Fee Collection by the International Organization for Standardization (ISO) In this case, the tolling server acts as a trusted party and a point-to-point communication is established between the RSU of the infrastructure (toll gantry) and the OBU embedded in the vehicle in order to enable the tolling transaction. Related work in the area of secure 5G communications and, section VI summarizes the contributions of the paper
