Abstract
For vehicular networks, the security and privacy face two major challenges. One is the open wireless medium and the other is the high-speed mobility of the vehicles. For the open wireless medium, eavesdropping and man-in-the-middle attacks may exist in the communication path. This is called an unsafe routing path. Based on quantum nature, quantum channel supported unconditionally secure communication. Classically, digital signature can support conditionally secure communication. So quantum channel is more secure than classical channel. For high-speed mobility of the vehicles, sender and receiver need location-release signature. This paper designs the technique of quantum entangled particle to perform quantum teleportation for solving quantum location-release signature. By using quantum nature, the proposed scheme can overcome two major challenges in the vehicular networks. This scheme uses multiple entangled particles to reconstruct the original quantum state among sharing party. Based on this function, a secret sharing message can be verified to provide the message recovery. Considering the security of the proposed scheme, impossibility of forgery and impossibility of disavowal can be achieved.
