A MULTI-LEVEL MODEL OF SECURITY, TRUST AND PRIVACY (STP) FOR VEHICULAR AD HOC NETWORK (VANET)

Road accident and traffic jam are the global issues in the current traffic system and
every year thousands of people died or injured due to road accidents. Vehicular Ad
hoc Network (VANET) is the infrastructure part of Intelligent Transportation System
(ITS). V ANET is a subclass of Mobile Ad Hoc Networks (MANETs). Security is one
of the key important factor and basic user requirement for successful implementation
of such kind of networks. This research work focuses on the how to achieve a
harmonious balance between Security. Trust and Privacy (STP) in VA NET. Our main
contribution in this research is an STP Model for VANET for implementation in a real
environment that will increase user contidence in using the Infrastructure for future
transportation systems. b) making it safer to use for content, information and safety
messages.
