Authentication in QoS Aware VANET: An Approach Based on Enhanced Digital Certificates

Vehicular Ad-hoc Networks (VANETs) indeed have significant potential to enhance transportation efficiency, accident prevention, and overall comfort. They enable communication between vehicles and road infrastructure, facilitating the exchange of entertainment and traffic information. This capability can lead to safer and more efficient transportation systems while improving the overall experience for drivers and passengers. The challenging and critical security requirements in VANETs, such as access management, authentication, and privacy protection, are essential for achieving the objectives of vehicle-to-infrastructure (V2I) and intervehicle (I2V) communications. These security measures ensure the integrity, confidentiality, and availability of communication channels, thereby enhancing transportation efficiency, accident prevention, and overall comfort within VANETs. In this study, we investigate the concerns of secure access control, authentication, and privacy protection in VANETs. In response to these challenges, we propose automobile authentication methods. This protocol is built on a toll-based certificate management system utilizing RFID tags and readers deployed on automobiles and toll booths. Additionally, we introduce a vehicular mobility management method and a VANET node attachment strategy that considers quality of service (QoS) requirements. This comprehensive approach addresses key security and operational aspects of VANETs.
