A Blockchain-Based Architecture for Traffic Signal Control Systems
This addresses security vulnerabilities in connected vehicle networks for traffic management, though it appears incremental as it applies blockchain to a specific domain.
The paper tackled data security issues in connected vehicle traffic signal systems by proposing a blockchain-based decentralized architecture, which was tested in simulation to defend against congestion attacks in the Intelligent Traffic Signal System (I-SIG) pilot program.
Ever-growing incorporation of connected vehicle (CV) technologies into intelligent traffic signal control systems bring about significant data security issues in the connected vehicular networks. This paper presents a novel decentralized and secure by design architecture for connected vehicle data security, which is based on the emerging blockchain paradigm. In a simulation study, we applied this architecture to defend the Intelligent Traffic Signal System (I-SIG), a USDOT approved CV pilot program, against congestion attacks. The results show the performance of the proposed architecture for the traffic signal control system.
