A secure message-passing framework for inter-vehicular communication using blockchain

Abstract

Due to exponential growth in the daily usage of vehicles, the traffic congestion and roadside accidents are increasing day by day. The communication among vehicles is critical to avoid the emergencies and to address the issue of congestion of vehicles. Internet of vehicles provides the communication channel between the vehicles, but existing solutions require a centralized communication system to distribute the message and to authenticate the source. This centralized infrastructure is subject to disturb the vehicular communication in case of server breakdown or due to any natural disaster where hardware stops working. Also, the centralized system proves to be costly as the communication of each vehicle necessitates access to the central server resulting in the more resource requirement. A secure distributed system is required to avoid the emergencies and reduce the traffic rate. To address the issues, we proposed a secure distributed messagepassing framework that does not require a centralized server, and it rates the credibility of message source using blockchain technology. The messages in the proposed system are forwarded through dedicated short-range communication protocol. To validate the proposed system, we have performed different simulations using SUMO, OMNET, and VEINS. The results demonstrated an increase in the average speed of vehicles that showed a reduced congestion rate. Moreover, our system identified the malicious vehicles with 77.1% accuracy.

Analysis of the Optimal Application of Blockchain-Based Smart Lockers in the Logistics Industry Based on FFD-SAGA and Grey Decision-Making

“…The uncertainty of this factor was due to the challenges of urban traffic congestion, distances to remote areas, invalid or wrong ad-dresses, locations that are difficult to find, no one being able accept the goods, buyer regret-not accepting the goods, bad parking, no elevators, etc. Such uncertainties are also the most worrisome situations for office workers [27][28][29].…”

“…A total of 1098 Taiwanese consumers were surveyed on their use of smart pickup lockers [27][28][29]. According to Table 9, based on the participants from the metropolitan areas in northern, central, and southern Taiwan, it can be seen that the top four rankings of office workers using smart lockers are the same as in Table 11.…”

Empowering Communications in Vehicular Networks with an Intelligent Blockchain-Based Solution

“…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.…”

“…Ref. [14] have used Blockchain technology for a secure distributed message passing. The proposed framework does not rely on a centralized server.…”

“…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.…”
