VANET Security Analysis on the Basis of Attacks in Authentication

Abstract

Elevation of technology in hardware, software and communication have lead to an idea of Intelligent Vehicles, which communicate via Vehicular Ad hoc Networks (VANET) to provide road safety and improved driving conditions. In VANETs, both multi-cast and uni-cast routing is applicable. These protocols can be used by an attacker to breach and endanger the network by accessing and manipulating information of the vehicle and communicating data. As authentication allows to trust both user and data, it requires considerable attention in the security framework of VANETs. Here, we provide a classification of attacks on the basis of security requirements to narrow down the parameters of consideration and comparison of previously proposed protocols in VANET. Pointing out security gaps regarding distinct threats, the classification will allow to designed new secure network control methods.
