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

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.
