Efficient Handoff Based Privacy Preservation for VANET

Sibil Joseph | Rajagopal.R

Abstract: VANET is a technology which make use of moving vehicles having location based senses to make a communication network for communicating between vehicle and the base station to transfer safety and non-safety related data like traffic alert, navigation, accident and multimedia applications and so on. Vanet having mainly three parameter they are vehicle, roadside unit and regional trusted authority. Roadside unit is the base station for particular region and regional trusted authority which act as a server. The security in privacy preservation and handoff between the base stations i. e. road side unit between different technologies is a serious issue in VANET. In the proposed system we are providing Elliptic Curve Diffie Hellman (ECDH) cryptography using public key where we have different key for encryption and decryption and we make use of digital signature for data integrity for security, the authorized authority have the access to track the vehicle using regional trusted authority server which have all information of the vehicle which make sense of non-repudiation in VANET and efficient vertical handoff between Road Side Unit based on signal strength and bandwidth between WLAN and WiMAX insure efficient coverage and multimedia access to the vehicle

Keywords: Elliptic Curve Diffie Hellman, Road Side Unit, Reginal Trusted Authority, Vertical Handoff
