Method and apparatusl for identifying pseudo base station and termina

Abstract

The invention provides a method and apparatus for identifying a pseudo base station, and a terminal. The method comprises the following steps: acquiring preset parameters in the LTE network where theterminal is located; when the preset parameters meet the corresponding pseudo base station judgment conditions, identifying the corresponding LTE base station in the corresponding network as the pseudo base station and / or the GSM base station corresponding to the LTE base station as the pseudo base station. The invention identifies that the corresponding LTE base station in the corresponding network is a pseudo base station and / or the GSM base station corresponding to the LTE base station is a pseudo base station by monitoring the preset parameters in the LTE network in which the terminal is located, In the process of cell selection and cell reselection, the defense scheme can be adopted before starting the registration process to provide a more secure and effective protection for the terminal.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method, device and terminal for identifying a pseudo base station. Background technique [0002] The GSM (Global System for Mobile communication, Global System for Mobile Communications) communication protocol adopts one-way authentication, that is, the terminal cannot authenticate the base station. The loophole in this communication protocol makes there are a large number of fake base stations on the market. They can pretend to be operator base stations and send text messages to connected users with any number. It is difficult to detect after forgery. At the same time, it also separates the user from the real operating network, causing communication interruption to the user. What's more, the terminal information obtained by the fake base station is used to cooperate with other devices to pretend to be a real user, and intercept important information such a...

In this way, it is more likely to implement more harmful attacks such as phishing, Trojan horses, and stealing verification codes, which will cause users to suffer great losses

[0006] In the prior art, the defense method for the fake base station in the GSM network is relatively mature, but the existing defense scheme for the fake base station in the GSM network cannot effectively defend against the dangerous attack from the fake base station in the LTE network, so in the LTE network The terminal in will face the security threat from the fake base station
