Verification of an Evolving Security Scheme in the Internet of Vehicles

Abstract

The security scheme of the Internet of Vehicles (IoV) protects the vehicles from network attacks. However, during the experimental deployment of the IoV, people usually pay attention to its function and performance, and only develop a security scheme empirically when security defects are found. When a security scheme becomes very complex, it is very difficult to find the security vulnerability and to modify it. In view of this, we propose a verification method to verify the security of an evolving security scheme. This method uses formal methods to verify the evolving security scheme, actively finds the security problems of the security scheme, and promotes the evolution of the security scheme accordingly. This method is applied to the scenario of the IoV and its security scheme—the method evolves the Internet of Vehicles configuration and the security properties, establishes a corresponding formal model, and then iteratively verifies this using a formal method. The approach can fully simulate the evolution process of a security scheme in the IoV during deployment, and can effectively find the corresponding security vulnerabilities, to promote the evolving security scheme in the IoV, which supports the feasibility and usability of the method.
