摘要：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, we use Multi-hop data dissemination protocol to address the vulnerability inherited by the vehicular ad hoc network. This technique includes self reconfigurable concept in which if an attack is detected in a path then an alternate path is provided for the data transmission which is done by piggy backing messages To enhance the security level in the VANET, HOLISTIC PROTOCOL has been developed using HIDDEN MARKOV MODEL and TRUST AWARE methods. Our simulation results show that our scheme highly detects and avoids the insider and outsider attack.
