A secure fire truck communication protocol for VANET

Vehicular ad hoc networks (VANETs) have been a research focus in recent years. VANET’s applications are mostly applied to the road safety and reduce the traffic accident earlier. Moreover, use VANET system can also help the emergency vehicles go to accident location as soon as possible. Therefore how to protect the transmission message is important. We propose a secure emergency vehicle transmission protocol for VANET to ensure the messages will not be revealed or stolen. The proposed scheme combines symmetric encryption and digital signature mechanism. On the other hands, the proposed scheme can achieve the mutual authentication, session key security, known-key security and prevent the known attacks Key-Words: VANET, Security,Symmetric encryption, Emergency vehicle, Session key
