Research of privacy protection mechanism for vehicles secure communication

Along with the development of the vehicle network, vehicle communication safety becomes the focus. On one hand, our scheme will use vehicles´ ID and RFID to map the interface of IPv6 and vehicles´ private key in CA. CA computes vehicle´s public key according the private key and then sent to the vehicle. On the other hand, vehicles communicate with RSUs in the public key distributed by CA to obtain anonymous keys. Then vehicles communicate with others using the anonymous key from RSUs. The vehicle´s true identity is relating to the keys distributed by CA. It ensures that the leak of anonymous keys will not lead directly identity leakage of the vehicles and users´. We apply PKI technology to vehicle ad hoc networks, and proposed to use anonymous public key to protect the vehicles and the drivers´ identities and privacy.
