Security Threats Mitigation for Internet of Vehicles Using Cryptographic Protocols

In the transportation domain, the Internet of Vehicles (IoV) enables vehicles to connect with their surroundings, including other vehicles, infrastructure, and various services, hence promoting information sharing for better user experience, safety, and traffic management. Given the increasing demand for autonomous vehicles, it is critical to address the network's security and privacy vulnerabilities. The paper aims to propose a secure chat protocol specifically tailored for enhancing communication in Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) relationships within the Internet of Vehicles (IoV). The protocol establishes a mutually agreed session key (Kabc) among vehicles and infrastructure components, ensuring that all exchanged messages are encrypted to protect sensitive data from eavesdropping and unauthorized access. By employing a certificate-based authentication mechanism, the protocol verifies the identities of communicating entities, thereby preventing impersonation attacks and ensuring trust in the information exchanged between vehicles and infrastructure systems.
