First embodiment
Fig. 3 is a basic flowchart of a pseudo base station identification method provided in this embodiment, where the pseudo base station identification method includes:
s301, the terminal obtains a target identification number according to a preset identification algorithm.
In this embodiment, the preset identification algorithm may adopt various algorithms, including but not limited to, obtaining a string of keys through an encryption algorithm, and binding the keys with the current communication number of the terminal to generate a target identification number; or a string of random numbers is generated through a random algorithm, and the random numbers are encrypted by an encryption algorithm to generate target identification numbers.
S302, when the terminal is connected with the surrounding base stations, the target number is sent to the base stations for registration.
After the terminal obtains the target identification number through a preset algorithm, when the terminal needs to exchange data with the outside, the terminal needs to be connected to surrounding base stations at first, and after the terminal is connected to the surrounding base stations to ensure smooth connection and successful connection, the terminal sends the target identification number to a connected server for registration. It should be noted that, in this embodiment, the surrounding base stations are all base stations that the terminal determines based on the operator network, and the pseudo base station generally operates in a manner of intercepting the user signal during operation, and the main operation manner is to transmit a signal to the terminal, and does not have a function of receiving and forwarding a signal, and cannot completely replace the function of the operator base station, so the base station that the terminal registers through the operator network is a relatively safe base station.
S303, the terminal receives the information issued by the base station, judges whether the identification number in the information is matched with the target identification number, and determines whether the base station is a pseudo base station according to the matching result.
When the terminal finishes registering on the base station, the base station and the terminal can perform normal data exchange, and after the terminal receives the information issued by the base station, the terminal can determine whether the base station is a registered base station or not by identifying the identification number contained in the information and comparing the identification number with the target identification used for registering so as to determine whether the base station is a pseudo base station or not.
In step S301, the terminal obtains a target identification number according to a preset identification algorithm. In this embodiment, a method for a terminal to obtain a target identification number according to a preset identification algorithm is provided, where the method includes, but is not limited to, obtaining a target identification according to a preset algorithm; and adding the target identifier into the communication number of the terminal to obtain a target identifier number. The predetermined algorithm includes, but is not limited to, a key generation algorithm, a random number algorithm, and the like.
In step S303, after determining whether the base station is a pseudo base station according to the matching result, the method further includes: when the identification number in the information sent by the base station and received by the terminal is not matched with the target identification number, the base station is a pseudo base station; and recording the identification number in the information. The pseudo base stations can be rapidly discharged and shielded by recording the identification numbers of the pseudo base stations, and the judgment speed of the pseudo base stations is improved.
After determining that the information currently received by the terminal is the information sent by the pseudo base station, the base station may be recorded.
