Security of vehicular communications
A transportation system is an environment that poses several challenges with regard to technology requirements. Because of the large number and high speed of Vehicles, technologies for Vehicular Communications (VC) and Intelligent Transportation Systems (ITS) must be scalable and robust enough to cope with these characteristics. Architectures and protocols for ITS thus need to be deeply examined and assessed for performance and scalability before their final adoption as part of a standard ITS framework.
