“…e computational cost of the BBAAS is analysed with Qi Feng et al's scheme [23], Dong Zheng et al's scheme [24], Zhaojun Lu et al's scheme [25], and Lun Li et al's scheme [26] as shown in Table 1. To find out the actual timing values of various cryptographic primitives of the proposed BBAAS, a 2 GHz laptop with 4 GB installed memory is used, with Cygwin 1.7.35-15 [27], PBC library [28], and GCC version 4.9.2 being considered.…”

Smart driving has become conceivable due to the rapid growth of vehicular ad hoc networks. VANETs are considered as the main platform for providing safety road information and instant vehicle communication. Nevertheless, due to the open wireless nature of communication channels, VANET is susceptible to security attacks by malicious users. For this reason, secure anonymous authentication schemes are essential in VANETs. However, when vehicles reach a new roadside unit (RSU) coverage area, the vehicles need to perform reauthentication with the current RSU, which significantly diminishes the efficiency of the entire VANET. Therefore, the introduction of blockchain technology has created opportunities for VANETs to resolve the aforementioned challenges. Due to the decentralized nature of blockchain technology, rapid reauthentication of vehicles is achieved in this paper through secure authentication code transfer between the consecutive RSUs. The security strength of the proposed blockchain-based anonymous authentication scheme against various harmful security attacks is proven in the security analysis section to ensure that it provides better security. In addition, blockchain, as presented in the performance analysis section, is used to substantially diminish the computational cost compared to conventional authentication schemes.

“…Existing research (e.g., [74,[76][77][78]) on decentralized identity management investigated the use of DLT for the mutual authentication of X-Nodes and controlling their identifying information. Previous work (e.g., [74,76]) on the authentication of X-Nodes used permissioned distributed ledgers and smart contracts (i.e., agreements that are formalized in program code and deployed to the distributed ledger). Other studies (e.g., [77,78]) present concepts related to self-sovereign identities, where users can manage data related to their identities on a distributed ledger.…”

Communication between vehicles and their environment (i.e., vehicle-to-everything or V2X communication) in vehicular ad hoc networks (VANETs) has become of particular importance for smart cities. However, economic challenges, such as the cost incurred by data sharing (e.g., due to power consumption), hinder the integration of data sharing in open systems into smart city applications, such as dynamic environmental zones. Moving from open data sharing to open data trading can address the economic challenges and incentivize vehicle drivers to share their data. In this context, integrating distributed ledger technology (DLT) into open systems for data trading is promising for reducing the transaction cost of payments in data trading, avoiding dependencies on third parties, and guaranteeing openness. However, because the integration of DLT conflicts with the short available communication time between fast moving objects in VANETs, it remains unclear how open data trading in VANETs using DLT should be designed to be viable. In this work, we present a system design for data trading in VANETs using DLT. We measure the required communication time for data trading between a vehicle and a roadside unit in a real scenario and estimate the associated cost. Our results show that the proposed system design is technically feasible and economically viable.

“…In [ 95 ], Lu et al also mentioned that the privacy-preserving authentication is the first priority issue for defending against attacks in VANETs and proposed a blockchain-based solution. They pointed out that the conventional centralized trusted authority (TA)-based solution has two main problems.…”

“…Second, a receiver must check a certificate revocation list (CRL) for the authentication of a message, which incurs a high computational overhead. To solve these problems, Reference [ 95 ] employs a permissioned blockchain approach to use multiple semi-trusted authorities in a decentralized manner. A Merkle Patricia tree is used to provide a cryptographically authenticated data structure.…”

The vehicular Internet of Things (IoT) comprises enabling technologies for a large number of important applications including collaborative autonomous driving and advanced transportation systems. Due to the mobility of vehicles, strict application requirements, and limited communication resources, the conventional centralized control fails to provide sufficient quality of service for connected vehicles, so a decentralized approach is required in the vicinity to satisfy the requirements of delay-sensitive and mission-critical applications. A decentralized system is also more resistant to the single point of failure problem and malicious attacks. Blockchain technology has been attracting great interest due to its capability of achieving a decentralized, transparent, and tamper-resistant system. There are many studies focusing on the use of blockchain in managing data and transactions in vehicular environments. However, the application of blockchain in vehicular environments also faces some technical challenges. In this paper, we first explain the fundamentals of blockchain and vehicular IoT. Then, we conduct a literature review on the existing research efforts of the blockchain for vehicular IoT by discussing the research problems and technical issues. After that, we point out some future research issues considering the characteristics of both blockchain and vehicular IoT.
