Design of authentication protocol for wireless sensor network-based smart vehicular system

Abstract The design of authentication protocol for a smart vehicle system is proposed, where vehicles are equipped with sensors and the sinks are placed along the road to receive and/or send data to sensors. The user monitors the vehicles by collecting data from sinks and performs analysis of the data by taking necessary action (if needed). Moreover, the system is using sensors in vehicles to provide a user-friendly platform to communicate with users. Now, the exchange of authentication message between authenticated entities are two important issues for successful implementation of a smart vehicular system. In the proposed vehicular system, there are three entities involve namely users, sink and sensor. In the same architecture, there is two set of communication between user to sink and sink to sensor are needed. In short, we have proposed an architecture of data traffic/movement in vehicular sensor network and authenticate the entities. In addition, we have analyzed our protocol with respect to security attacks and found that it is strongly protected against security attacks. Furthermore, the proposed protocol is relatively better in terms of overhead such as computation and communication.
