QoS-Based Secure Data Communication for Software-Defined Autonomous Vehicles Using Blockchain

Abstract

Data security in autonomous vehicles is of primary importance due to the possibility of cyberattacks on these interconnected and complex systems. As these vehicles are equipped with a number of sensors, software, and communication infrastructure, they are more vulnerable to different types of security issues. In this article. blockchain-supported QoS-based secure data communication (QoS-SDC) is proposed for high-speed, software-defined autonomous vehicles. This proposed mechanism will provide a promising solution for delivering protected data among autonomous vehicles. This model is evaluated by using the NS3 simulator, and the simulation results exhibit satisfactory secure data transactions.
