Security of Vehicular Network


What are Vehicular Networks?

Vehicular Networks (also known as VANETs) are a cornerstone of the envisioned Intelligent Transportation Systems (ITS). By enabling vehicles to communicate with each other via Inter-Vehicle Communication (IVC) as well as with roadside base stations via Roadside-to-Vehicle Communication (RVC), vehicular networks will contribute to safer and more efficient roads by providing timely information to drivers and concerned authorities. The interesting research area of Vehicular Networks is where ad hoc networks can be brought to their full potential.

Security of Vehicular Networks

To become a real technology that can guarantee public safety on the roads, vehicular networks need an appropriate security architecture that will protect them from different types of security attacks. Leveraging on the expertise of LCA in the domains of networking and security, we are exploring the different security aspects of vehicular networks, including:
