Global Roaming Trust-based Model for V2X Communications

Abstract

Smart cities need to connect physical devices as a network to improve the efficiency of city operations and services. Intelligent Transportation System (ITS) is a key component of smart cities. ITS supports the communication between vehicles to improve the driving experience and achieve active transportation. The communication is provided using Vehicleto-Everything (V2X) communication technology. Cyber-security is currently one of the main challenges facing V2X technology. A V2X communication link is vulnerable to various cyberattacks including internal and external attacks. Internal attacks cannot be detected by traditional security schemes because the compromised nodes have valid credentials. Thus, a trust model is needed to defend against them. In this paper, a global roaming trust-based security model is proposed for V2X communication. Each vehicle has a global knowledge about malicious nodes in the network. In addition, we conduct various experiments with different percentage of malicious nodes to measure the performance of the proposed model. Simulation results show that the proposed model improves False Negative Rate (FNR) by 33.5% in comparison with the existing model.

Vehicular Platooning to be Secure against Cybersecurity Attacks

“…Travel demand for humans and freight observed huge increased in number and intensity. This intensity lead increased number of motors not only on urban road but also for long route [1].Along with facilitation, this massive amount of motors bring some problems with this. Major problems are accidents, air pollution and congestion [2].…”
