摘要
The present invention provides a vehicle node location privacy protection system and method in conjunction with a PMIPv6 framework. An LBS and OBUs register with a TA, and the LBS obtains a certificate and a private key issued by the TA and calculates a public key of the LBS. The OBUs obtain a series of pseudonyms and corresponding public keys and private keys issued by the TA. The OBUs generate location service requests by using the pseudonyms and location information, and send the location service requests to an LMA by means of MAGs, and the LMA aggregates the location service requests of the OBUs and then send same to the LBS. The LBS aggregates responses of all OBUs accessing the same LMA and transmits same to the LMA by taking the pseudonyms of the OBUs and corresponding response messages as responses, the LMA transmits the aggregated response to corresponding MAGs for broadcasting. The OBUs under the same MAG obtain responses corresponding to requested location services according to the pseudonyms of the OBUs. The present invention realizes vehicle node location privacy protection in conjunction with the PMIPv6 framework, and the LMA sends a location-based request to the LBS and accepts a response message instead of the OBUs according to the idea of group, so that location privacy of the OBUs is ensured.
