Problems solved by technology

[0006] (1) Cannot be directly used in VSN
Since the user's movement track is restricted by the road, the request message may not be able to reach the location server, which makes the LBS service fail
[0007] (2) The credibility of users under VSN is not considered
The disadvantage is that the invention has a single function and does not consider the location privacy leakage problem caused by the user's untrustworthiness

Embodiment

[0069] The following simulation experiment is carried out based on the above method. The implementation method of this embodiment is as described above, and the specific steps will not be described in detail. The following only shows the effect of the simulation experiment results.

[0070] The parameters of the simulation experiment are configured as follows: the highway involved in the experiment generates the user’s movement trajectory according to the VanetMobiSim platform, its intelligent traffic model is polito.uomm.IDM_LC, the map size is 5Km*5Km, the maximum number of traffic lights is 20, and the maximum number of mobile users is 300, the driving speed range is [0-40Km / h], the running time is 100s, the location server is in the center of the map, the communication radius is 300m, the user's social trust value is randomly generated, and the user sends a location query request message. In the experiment, the performance of the present invention and the HSLP method were c...

Abstract

The invention discloses a friend forwarding based location privacy protection method of a vehicle-mounted social network. In the location privacy protection method of the vehicle-mounted social network, a location inquiry request massage, which is submitted to a location service, by a mobile subscriber can reach a location server through friend forwarding, and inquiry information fed back by the location server is acquired, so that the location privacy of the mobile subscriber is protected and the success rate of enabling the request massage to reach the server is improved. The friend forwarding based location privacy protection method of the vehicle-mounted social network has the following beneficial effects that (1) a friend forwarding mechanism is adopted to prevent malicious attackersto do collusion attacks, and the location privacy protection intensity of the mobile subscriber is improved; (2) the message reaching success rate of the mobile subscriber can be maintained to be 0.9or more, and the requirements of the subscriber on location service business can be met.

Description

technical field [0001] The invention relates to the technical field of wireless network communication, in particular to a method for protecting location privacy of a vehicle-mounted social network based on friend forwarding. Background technique [0002] Vehicular Social Network (VSN) is an open-structure social network composed of passengers and drivers communicating with each other through DSRC protocol or 4G / 5G technology. Location Based Services (LBS) is a value-added service provided by the combination of VSN and satellite positioning system. It obtains the user's location information through a set of positioning technologies and provides it to passengers / drivers and location servers. location-related business. However, while location-based services are placed on the business with the most value-added potential, they also pose a great threat to people's privacy. Attackers can track the user's movement trajectory by eavesdropping on location information without authori...
