A Secure Ambulance Communication Protocol for VANET

摘要: Vehicular ad hoc networks (VANETs) have been a research focus in recent years. VANET's main applications are enhancing road safety and reducing traffic accidents. Moreover, the VANET system can also reduce time it takes for emergency vehicles to arrive at accident location. The security of transmission messages is utmost importance, protect we propose secure ambulance communication protocol ensure that will not be revealed or stolen. proposed scheme combines symmetric encryption, message authentication codes digital signature mechanisms, thereby achieves non-repudiation, availability, integrity, confidentiality, mutual authentication, session key security, known-key ability prevent known attacks. Finally, with NS2 simulation results based on realistic vehicle density statistics Taipei city map, argue our effective real scenarios.
