Abstract

Automobiles are becoming increasingly important in our day to day life. Modern automobiles are highly computerized and hence potentially vulnerable to attack. Providing many wireless connectivity for vehicles enables a bridge between vehicles and their external environments. Such a connected vehicle solution is expected to be the next frontier for automotive revolution and the key to the evolution to next generation intelligent transportation systems. Vehicular Ad hoc Networks (VANETs) are emerging mobile ad hoc network technologies incorporating mobile routing protocols for inter-vehicle data communications to support intelligent transportation systems. Thus security and privacy are the major concerns in VANETs due to the mobility of the vehicles. Thus designing security mechanisms to remove adversaries from the network remarkably important in VANETs. This paper provides an overview of various vehicular network architectures. The evolution of security in modern vehicles. Various security and privacy attacks in VANETs with their defending mechanisms with examples and classify these mechanisms. It also provides an overview of various privacy implication that a vehicular network possess.
