VANETs are an emerging research area and currently research on security is ongoing in wireless technology. Which includes solving the traffic related problems and provides safety for life's of people. Attackers could be able to reroute traffic if they insert malicious messages into traffic information systems. Knowledge able attackers will be able to access key material in vehicles they physically own. Using the obtained keys, attackers can generate wrong information or modify information. To strengthen the security and to detect the insider attack, the authors use multi-hop data dissemination protocol to address the vulnerability inherited by the vehicular ad hoc network.
