Authentication methods for internet of vehicles based on trusted connection architecture

This paper proposes an authentication protocol based on a trusted connection architecture to manage the security and reliability of the cloud service environment during the communication process, improve the trust of the cloud service platform toward vehicles, and ensure that vehicle terminals have reliable access to cloud services. Compared with prior Internet of Vehicle (IoV) authentication schemes, our scheme is the first to include platform identification in the authentication process. Based on the characteristics of the trusted connection architecture, the components that constitute the platform can be assessed for security by verifying the vehicle platform identity and platform integrity metrics, thereby eliminating internal threats. In addition, the protocol proposes an authentication scheme for the IoV environment, in which the trusted authority only needs to generate the user's partial key based on the identity, thereby avoiding the key escrow problem common to identity-based cryptosystems. Finally, the scheme is proven to be highly secure using various approaches, such as Syverson-Van Oorschot (SVO) logical analysis, simulated authentication via automated validation of internet security protocols and applications (AVISPA), and informal security analysis. In the identity authentication step, our method has low computation and communication overhead when compared with other schemes according to the performance analysis results.
