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