An Attack Resistant of Malicious Nodes for Securing Vehicular Adhoc Networks by an Encryption Alert
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Vehicular Ad hoc Network (VANET) is an autonomous wireless network comprising of moving vehicles. A small communication unit is installed in the devices that are capable of transmitting its GPS (Global Positioning System) position and gather important information from other vehicles and road side junctions. As vanet is an open architecture which means the underneath technology being used is essentially either wifi or Bluetooth such networks often referred as public network .one of the most challenging issues of any public network is to ensure privacy and trustworthiness of the data. In vehicular ad hoc network as the vehicle moves with rapid speed the link itself varies with significantly different vehicle will have a enter communicable link which will be keep on changing with the mobility movement of the vehicle .In such a highly dynamic network to determine which packets are malicious or which nodes are malicious is extremely difficult, Therefore the proposed work analysis a novel hybrid technique for trust management and privacy preservation in vanet Our trust management system will enable the nodes to determine the validity of a specific packet, this is known as packet trust or data trust ,validity of the sender also known as node trust ,validity of the type of message is being conveyed also known as functional trust. our entire work demonstrate how to detect and prevent malicious nodes and attacks by analyzing various trust models through the GPS data exchange between the nodes among themselves and the node in the road side unit. The work is simulated using vanetsim which is a java based real time vanet simulator. A result shows that the accuracy of the detection of the attacker and an attack model is extremely efficient in our case.
