Last few years, vehicular networks are gaining more and more attraction from the researchers and the automobile industries. 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. First module is based on attackers and the attacks. An attacker is one of the most significant entity who can intentionally change the behavior of the other entities (Vehicle or Infrastructure) in the network. It is important to study and analyze the attackers and attacks before designing the life saving networks. Second module is based on trust and trusting computing technology. Trusted platform module (TPM) is a hardware security module and plays a major role to develop trust in vehicles. Purpose of this study is to develop trust in vehicular network. This trusted vehicular network model enforces all the entities of the network to behave in a specified manner. We believe that this trusted model would be more helpful in serving the users of the vehicular environment.
