Description

Technical field [0001] The present invention belongs to the user-positioning security technology in the mobile communication network, in particular, to a 5G positioning true value detection and attack traceability method, system, equipment, and application. Background technique [0002] At present: With the rapid development of 5G, network performance and capacity have been continuously optimized and improved, the number of network infrastructure has also increased significantly, so that the base station-based wireless positioning mode has broad application prospects. The base station can extract the relevant parameters from the wireless signal from the user equipment to obtain positioning information of the device. This approach can effectively reduce the power consumption of terminal equipment, but also realize precision positioning in special environments such as indoor equipment, bringing great convenience to people's lives. Future 5G network base station (BS) will have a ver...

AI Technical Summary

Problems solved by technology

The existing method does not consider the interference and attack that the user may encounter during the uplink wireless signal transmission, causing the base station to obtain inaccurate or insecure positioning parameters; it also does not consider the possible attack on the base station, if it participates in positioning, it may directly provide false information. Positioning parameters, resulting in decreased positioning accuracy or even false positioning

Therefore, there are major security flaws in the existing solutions, which cannot protect the possible attacks in the positioning system, cannot guarantee the security, feasibility and accuracy of positioning data, and cannot complete the attack detection on users and the traceability of attacks on malicious base stations.

[0004] Through the above analysis, the problems and defects of the existing technology are as follows: the existing scheme has major security flaws, cannot protect the possible attacks in the positioning system, cannot guarantee the security, feasibility and accuracy of the positioning data, and cannot complete the user's monitoring. Attack detection and attack source tracing on malicious base stations

[0005] The difficulty in solving the above problems and defects is that the existing technology cannot guarantee the security and reliability of the positioning system. For example, when the user transmits the uplink signal, the existing solution only considers the security of the signal transmission and cannot guarantee the positioning Safe extraction of parameters, especially when multiple base stations participate in positioning, it is impossible to identify the interfered base station and its positioning parameters
