Hash function and DSRC based secure communication protocol for VANET-WAVE architecture

Abstract

The research and development community has recently become more interested in automotive adhoc networks due to their extensive application possibilities in traffic control and the social networking of automobiles. Vehicle-to-vehicle (V2V) and vehicle-toinfrastructure (V2I) communication is made possible through vehicular adhoc networks. For safety and other reasons, vehicles connected by vehicular adhoc networks exchange messages. Particularly vulnerable to security and privacy breaches are safety messages. In every vehicle-to-vehicle and vehicle-to-infrastructure communication exchange, information about the vehicle, the driver, and the authentication of transferred information are crucial considerations. A Dedicated Short Range Communication (DSRC) protocol is incorporated with the Wireless Access Vehicular Environments architecture in the current communication. The DSRC protocol incorporates a secure key exchange method to encrypt and decrypt the basic safety messages sent between the vehicles at the receiving end. The end-to-end delay of the communications is barely changed, however the performance of the DSRC is slightly impacted by the encryption and decryption. Our findings demonstrate that, despite a modest drop in DSRC performance, our protocol is too secure for the BSM (Basic Safety Message) to be cracked.
