Abstract: There is an pressing need of effective trust management for vehicular ad-hoc networks (VANETs), given the dire consequences of functioning on false data sent out by malicious peers during this context. In this paper, we have a tendency to initial discuss the protection & study of assorted attacks in VANET and comparison of assorted attacks in VANET. We tend to then survey of VANET Security needs & trustworthy computing to boost security in network. Supported these studies, we recommend desired properties towards effective trust management in VANETs, putting in clear goals for researchers during this space.
