Abstract—The communicating nodes in Ad-hoc networks are dynamic in nature in comparison with the traditional network nodes which appears in any fixed network infrastructure and usually Ad hoc networks are deployed in specific environment to achieve certain goals. Due to these features security challenges also increases in comparison with other traditional networks. We can say that the method used in fixed infrastructure networks cannot be directly applied in the case of Adhoc networks. So a short-range wireless channel has security problems that differ from those of more conventional networks. Vehicular Ad hoc networks (VANETs) are a subgroup of Ad hoc networks with the distinguishing property that the nodes are vehicles. This paper focuses on the security issues concerned with Vehicular Ad hoc-networks which are the most emerging forms of Ad hoc networks now days. Basically security is the main concern under the umbrella in the case of Ad hoc networks because user private data need to be protected by the authorities such that from location profiling and from other attacks on their privacy. Features like system availability and security can be achieved only with the coordination among system operators and vehicle manufacturers so that the faulty units can be identified easily.
