Token-based Authorization and Authentication for Secure Internet of Vehicles Communication

Internet of Vehicles (IoV) communication platform provides seamless information exchange facilities in a dynamic mobile city environment. Heterogeneous communication is a common medium for information exchange through autonomous resources distributed and accessed using infrastructure units. Cyber-Cyber-security is a primary concern in accessing autonomous information from the distributed resources due to anonymity and different types of targeted adversaries. This paper proposes token-based authorization and authentication (TAA) for securing IoV communications. The proposed method relies on blockchain technology and random forest learning for authorization and key management for authentication respectively. In this process, frequent chance in tokens and key update features are restricted in a view to maximize the seamlessness in information exchange. Authentication is preceded with the knowledge of the data classification without errors to prevent additional overhead. Blockchain based authorization helps to update specific fields of the tokens so as to retain the communication ratio by reducing vehicle-to-vehicle losses. The performance of the proposed method is assessed using appropriate simulations for the above discussed metrics by varying the vehicles density, error rate, and classification sets.
