Security and privacy enabling solution for vehicular networks

Abstract

Vehicular Ad-Hoc Network, better known as VANET is a promising new technology which combines the capabilities of different wireless networks in vehicles enabling Intelligent Transportation System (ITS). Vehicular Ad-Hoc networks provide communication between on-board unit (OBU) already integrated in the vehicles and road-side units (RSUs) consisting of on-board sensors, processing modules, and wireless communication modules. Immense amount of research is going on both by industry and academia. In vehicular communication because of the high speed of vehicles frequent handovers occur and hence there is always a requirement of secure and fast authentication for a seamless handover to take place. In this paper we propose an authentication scheme that will not only provide security and privacy but also will reduce the storage and communication overhead increasing the efficiency. © 2012 ICST Institute for Computer Science, Social Informatics and Telecommunications Engineering.
