Prevention of hacking in vanets using network security

Abstract

Vehicular ad hoc networks (VANETs) plays an important role in vehicle transportation system and provides vast benefits in safety and Security applications. The basic idea of VANET is to send a message to a different vehicle which is close by from the source when it is in danger. VANET also provides an algorithm for each vehicle to cross from one signal to another signal without causing accidents with the help of a Road Side Unit (RSU). This message can also be sent to various vehicles as well. VANETs although do not provide enough security to send a message to a particular destination. The propound work is to add a connection sensitive junction based shortest path routing protocol (CISRP) for VANETs in a dynamic atmosphere and to prevent the messages or packets from being hacked and altered. The results show a change in the routing protocol and decreases the path as well. The attacks also concern the passengers since the VANETs sometimes can be altered and sent to other vehicles with misinformation,thus this leading to a misintepretation. This paper explains about the safety challanges faced by VANET and the security requirements to protect the information.
