Security in Vehicular Ad hoc Network (VANET) using Trusted Platform Module (TPM): A Survey

Abstract

Vehicular Ad hoc Networks (VANETs) are gaining more attention from automobile industries due to
user safety on highway. However, security and safety critical issues need to be resolved before
deployment of VANET in real environment. In this paper, we are providing a comprehensive survey
on the usage of trusted platform module (TPM) in VANET. VANET is a open wireless environment
where vehicle can communicate with other vehicles and also with roadside unit where any infected
rogue vehicle can perform malicious actions on fellow vehicles. Security threats caused by rogue
vehicles can endanger life of passengers. Trust is an important key factor and it can be introduced
inside VANET environment using TPM hardware. The core purpose of this survey is to highlight the
security threats in VANET and provide security architecture built upon TPM to mitigate all
discussed threats.
