The life saving factor is the key issue in this regard. Trust is key part of security and it is undoubtedly a necessity to develop trust in vehicular network. The main aim of this paper is to propose a trust model for vehicular environment. The proposed model contains two different modules.

The main idea behind trusted computing is the hardware based TPM which contains active security modules that supports web of trust to be built within components of the network. We propose a new model for web of trust within vehicular to handle all types of attacks and maintain the integrity of messages.

The trusted Platform module (TPM) is used inside the vehicle and plays a key role to establish trust within the vehicle and also with other vehicles and network infrastructure. In this paper, a protocol is proposed which is based on a property based attestation (PBA) also known as Vehicular Property based attestation Protocol (VPP). In this proposed protocol, it is not based on the properties of the hardware and software of the vehicle; rather it depends on the static or dynamic properties of the system which has been configured. We would expect that the protocol will fulfill the need for a more secure and trusted mechanism for users using the safety and non-safety applications and services in the vehicular network.

Trust and Privacy are two major components of security and dynamic topology and high mobility of vehicles make it more challenging task for end users in network. We propose a new and practical card-based scheme to ensure the Security, Trust and Privacy (STP) in vehicular network. Proposed scheme is based on security hardware module i-e trusted platform module (TPM).

Hardware plays more important role to provide a security in vehicular environment. In this paper we do comparative study of three basic security hardware modules (Event Data Recorder, Tamper Proof Device and Trusted Platform Module). There are many parameters for selecting the security modules but cost is the most important one. Automotive industry plays vital role to resolve the cost issue and make it easier for commercial users to adopt a new vehicular technology.

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.

In this paper, the role of the end user in a vehicular network will be discussed in detail and three levels of trust grades for users will be proposed. It is necessary for secure vehicular communication that the user’s role in the network should be in a positive direction, and other users should take more benefits from this new future technology.
