Abstract
The rapid advancement in the area of the Internet of Vehicles (IoV) has provided numerous comforts to users due to its capability to support vehicles with wireless data communication. The exchange of information among vehicle nodes is critical due to the rapid and changing topologies, high mobility of nodes, and unpredictable network conditions. Finding a single trusted entity to store and distribute messages among vehicle nodes is also a challenging task. IoV is exposed to various security and privacy threats such as hijacking and unauthorized location tracking of smart vehicles. Traceability is an increasingly important aspect of vehicular communication to detect and penalize malicious nodes. Moreover, achieving both privacy and traceability can also be a challenging task. To address these challenges, this paper presents a blockchain-based efficient, secure, and anonymous conditional privacy-preserving and authentication mechanism for IoV networks. This solution is based on blockchain to allow vehicle nodes with mechanisms to become anonymous and take control of their data during the data communication and voting process. The proposed secure scheme provides conditional privacy to the users and the vehicles. To ensure anonymity, traceability, and unlinkability of data sharing among vehicles, we utilize Hyperledger Fabric to establish the blockchain. The proposed scheme fulfills the requirement to analyze different algorithms and schemes which are adopted for blockchain technology for a decentralized, secure, efficient, private, and traceable system. The proposed scheme examines and evaluates different consensus algorithms used in the blockchain and anonymization techniques to preserve privacy. This study also proposes a reputation-based voting system for Hyperledger Fabric to ensure a secure and reliable leader selection process in its consensus algorithm. The proposed scheme is evaluated with the existing state-of-the-art schemes and achieves better results.
Highlights
Internet of Vehicles (IoV) networks are able to improve driving safety, efficiency, and traffic management using On-Board Units (OBUs) for data communication, with or without prior infrastructure
The literature review concluded that most of the security services can be achieved by the implementation of blockchain
This paper provides a brief introduction to IoV, Hyperledger Fabric, consensus algorithms, privacy, and anonymization techniques, in conjunction with the additional terminology necessary to understand the problem statement and proposed scheme
Summary
Internet of Vehicles (IoV) networks are able to improve driving safety, efficiency, and traffic management using On-Board Units (OBUs) for data communication, with or without prior infrastructure. As a result of the increase in the number of users and the open nature of these networks, security threats are a challenge Security requirements such as authentication, the privacy of vehicle nodes, and audibility are necessary to avoid these networks from different types of attacks, such as impersonation attacks, and spreading of false information. If integrity is not provided during message transmission, vehicle nodes can misbehave and alter the content of a message In such a case, the receiver only knows that the message was sent by a legitimate vehicle, and they would be responsible for any damage. Privacy is a core feature of IoV, but traceability is necessary in the case of any unwanted activity in a network. The privacy of the vehicle should be revoked and punished
