“…Furthermore, several Blockchain-based solutions for vehicular networks have been proposed for secure key management (e.g., [10]), data collection and sharing (e.g., [4,7,9,11,12]), as well as vehicle communications (e.g., [1,3,5,8,13,14,18]). With respect to key management, [10] have designed a framework to manage security keys within an heterogeneous vehicular network.…”

“…Vehicles are, therefore, evolving toward becoming cyber-physical systems that create Vehicular Ad-hoc NETworks (VANET) through which relevant information is timely-provided to a wide range of stakeholders (including drivers, road traffic authorities, manufactures, maintenance companies, and insurance companies) for various applications [2]. Collecting and disseminating information on life-threatening traffic events with VANET have, particularly, become of utmost importance [3].…”

“…In the particular field of transportation, various Blockchain-based solutions have been proposed, for example, for interconnected smart vehicles (e.g., [7]), ITS (e.g., [8]), forensic applications (e.g., [9]), secure key management (e.g., [10]), data collection and sharing (e.g., [7,11,12]), and vehicle communications (e.g., [1,3,5,8,13,14]). In spite of the relevant approaches that have addressed vehicular communications, Blockchain solutions are still computationally expensive.…”

Blockchains have emerged over time as a reliable and secure way to record transactions in an immutable manner in a wide range of application domains. However, current related solutions are not yet capable of appropriately checking the authenticity of data when their volumes are huge. They are not also capable of updating Blockchain data blocks and synchronizing them within reasonable timeframes. This is the case within the specific context of Blockchain vehicular networks, where these solutions are commonly cumbersome when attempting to add new vehicles to the network. In order to address these problems, we propose in this paper a new Blockchain-based solution that intelligently implement selective communication and collaborative endorsement approaches to reduce communications between vehicles. Our solution represents the vehicles of the Blockchain as intelligent software agents with a Belief–Desire–Intention (BDI) architecture. Furthermore, we propose an approach based on multi-endorsement levels to exchange data of varying sensitive categories. This approach, which is based on endorsing scores, is also used to shorten the admission of new vehicles into the Blockchain. We run simulations using the Hyperledger Fabric Blockchain tool. Results show the efficiency of our solution in reducing the processing times of transactions within two different scenarios.

“…The BC‐based vehicular network can operate in a distributed manner to build a new, reliable, and secure distributed transport management system. Some efforts have already been made in which BC is used to resolve critical message dissemination issues in VANET Energy : In the energy sector, IoT is playing an important role as sensors are being installed on pipelines, valves, or other assets to help in monitoring equipment over time, to identify flaws, and to prevent leaks.…”

Blockchain is a key technology that enables cryptocurrencies such as Bitcoin, Litecoin, etc. In recent years, researchers have ventured into tapping the potential of blockchain‐based ecosystems beyond cryptocurrencies. This paper explores the convergence of blockchain with the Internet of things (IoT) and its improved versions like software‐defined network (SDN)–based IoT, which are upcoming technologies in the area. This paper gives a brief description of the IoT and its challenges, especially the security aspects. It also discusses how blockchain concept can further resolve these challenges on the SDN‐based IoT platform. This paper first discussed the evolution of conventional IoT to the SDN‐based IoT, which can resolve many drawbacks of a conventional IoT system. Also, it is focused on how the concept of blockchain can be converged with SDN‐based IoT system to further improve its security aspects. Although the convergence of these different technologies has resulted into many advantages, many associated challenges still remain. This paper highlighted these challenges and opportunities to discover many other research issues that need to be resolved. The details of current literature on the same issue has also been highlighted in this paper.
