A Group Authentication Method for Public Transportation Platooning

With the rapid progress of the use of autonomous vehicles, the transportation industry is encountering significant transformations. Platooning structures are one of these advancements that help improve the safety of autonomous vehicle networks. These formations hold the potential to reshape the traffic flow of collective vehicles on the roads. Clearly, ensuring the security and privacy of such systems becomes essential. In this work, we propose a protocol that seamlessly integrates into public transportation platooning while prioritizing system security. The main focus of this protocol is providing a lightweight vehicle authentication method for the platoon systems that not only ensures secure authentication but also protects privacy for all involved entities.
