Method and system for identifying pseudo base station

Abstract

The invention relates to the field of communication, in particular to a method and a system for identifying a pseudo base station, and aims to efficiently and accurately identify the pseudo base station. The method comprises the following steps: acquiring base station attribute information of a target base station, generating a corresponding base station code by adopting a deep neural network model, comparing the base station code with pre-stored sample data, and judging whether the target base station is a pseudo base station or not according to a comparison result and a reported feedback result. The base station code is generated on the basis of the base station attribute information containing the characteristic data for uniquely identifying the target base station; therefore, the basestation code can effectively reflect the attribute and behavior characteristics of the base station; even if law breakers frequently modify and reconfigure a part of characteristics of the pseudo basestation to prevent tracking, only a small amount of characteristic data is modified, so that the base station code can still be used as an important basis for accurately identifying the pseudo base station, thereby effectively improving the identification accuracy of the pseudo base station, reducing the identification time delay, and being quick and efficient.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for identifying pseudo-base stations. Background technique [0002] In the 2G era, both the Global System for Mobile Communication (GSM) standard and the IS95 standard use one-way authentication for authentication, that is, only the base station communicates with the user equipment (UserEquipment, UE) (such as a mobile phone) Authentication is performed, but the user terminal does not perform authentication on the base station. When the user terminal works in the 2G standard, once the signal strength of the pseudo base station is greater than the signal strength of the real base station, the user terminal will access the pseudo base station. [0003] Once the user terminal is connected to the fake base station, it will face the following threats: online real-time transaction threat, which may hijack the entire transaction; false SMS fraud threat; mobile ...

Problems solved by technology

[0007] However, the technology of pseudo base stations has been upgrading and configuration parameters will be changed at any time. Therefore, if the pseudo base station is to be successfully identified, the base station parameter information database must be updated in time. Once the update is not timely, the pseudo base station cannot be successfully identified. To a certain extent, bring losses to users
