Towards Improving Security in VANET: Some New Possible Attacks and Their Possible Solutions

Abstract

Vehicular ad hoc network (VANET) is taken more attention from the end user due to its potential safety and non-safety applications. The basic design objective of these applications to serve the users and provide safety of human lives during their journey. The role of the end user is more prominent for next generation vehicular networks. An attacker is one of type of end user, but their role in the network is negative and creates problems for other components of network. So in this paper, we will discuss two new types of attacks which are called road side traffic signal attack and also Internet attack in vehicular network. The authors will explain an attacker's behaviour and how he/she will launch an attack on a road side traffic signal and Internet services and create problems for other users of network. Through different scenarios, it will explain the effect of these attacks on other components of network. Trusted Platform module (TPM) is a security hardware module and it is provided the secure communication in network, so we will discuss in detail how this security module will handle these newly address attacks in network.
