An Overview on Vehicular Ad Hoc Networks Security

Abstract

The popularity of Vehicular Ad-hoc Networks (VANET) is on the rise as a response to increasing accident rates. VANET offers a range of safety applications with a primary goal of saving human lives. Driving on the road is not just about reaching a destination; it’s about navigating the journey. It also fosters connectivity between vehicles to create a system where information can be exchanged wirelessly and used to make driving decisions in real time, thus facilitating smooth traffic flow. The term nodes in this situation are used to depict vehicles that are moving at different velocities. The main goal of VANET is to enable the exchange of data between vehicles and between vehicles and infrastructure by adopting. VANETs can be significantly enhanced by merging blockchain and quantum computing to improve their security. Blockchain provides a decentralized mechanism to protect the security and safety of the system. It ensures high protection for moving vehicles, while quantum computing resists attacks. The security and efficiency of the transportation system are also of interest to Intelligent Transportation Systems (ITS). The growth of VANET is due to the increasing popularity, and the main problem for this kind of network is safety. It has to be really safe because any weak point in such a system can lead to terrible accidents, which may take human lives; these fatal incidents will not only lead to a loss of lives but also affect the integrity of those involved. The security of VANET frameworks faces challenges of real-time security with the existence of restrictions, responsibility, fast mobility, little room for errors, and key distribution. The analysis of cryptographic, quantum, and security protocols is vital.
