Abstract
The invention is suitable for the information safety technology field and provides the vehicle positioning system of a parking lot and a vehicle positioning method. The system comprises a positioningbase station and a server in the parking lot. The positioning base station sends a positioning data packet to the server. The server generates the second hashed value of second integration informationaccording to a preset MD5 function and the second integration information and detects whether the second hashed value is the same with a first hashed value. If the second hashed value is not the samewith the first hashed value, the positioning data packet is determined to be tampered. The positioning data packet is marked as the tampered positioning data packet. A preset positioning reliabilitygeneration model and the number of the tampered positioning data packets are used to generate the current positioning reliability of the positioning base station. Whether the current positioning reliability is less than a preset threshold is determined. If the current positioning reliability is less than the preset threshold, the positioning base station is determined to be the malicious positioning base station, and the positioning data packet sent by the malicious positioning base station is shielded. In the invention, the malicious positioning base station can be prevented from bringing a safety threat to vehicle positioning so that the safety of the vehicle positioning is increased.
Description
technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a vehicle positioning system and a vehicle positioning method for a parking lot. Background technique [0002] With the rapid development of the mobile Internet, various application technologies based on the mobile Internet have emerged. Among them, the Internet of Vehicles system uses the network to intercept the attribute information and static and dynamic information of the vehicle, and effectively supervises the running state of the vehicle according to different functional requirements and provides comprehensive vehicle management services. And the popularity of mobile Internet has developed rapidly. [0003] However, the existing vehicle positioning system in the parking lot is difficult to identify malicious positioning base stations, which is not conducive to improving the security of vehicle positioning. The reason is that the positioning base ...
