The successful introduction of vehicular communication has to posses the design of robust security architecture that should be able to cope with security threats. Ad hoc networks are a new wireless networking paradigm for mobile hosts. Vehicular networks are likely to become the most relevant form of mobile ad hoc networks.. In this paper, the authors have discussed the various suggested security architectures by the researchers over the time. In recent years, the use of wireless communication devices has quickly increased. Vehicular network allow nodes like vehicles or road-side infrastructure units, to communicate with each other over single or multiple hops.
