Abstract : Vehicular Ad hoc Network (VANET) are used to provide inter vehicular communication. VANET uses wireless mode for communication between vehicles so there is a lot of possibilities to get interrupted or attacked by hackers since each message which are transmitted are broadcasted messages in VANET communication. Therefore, a secure and confidential transmission of messages plays a major challenge in VANET. This paper focuses on VANET Architecture, Security mechanism and various types of attacks and challenges faced in communication. By using the proposed survey, a detailed explanation of various attacks and security challenges are discussed in this paper.
