Electronic fraud base station communication equipment

What is a fake base station?

A malicious or fake base station is a well-known security issue in mobile networking. For example, there are open-source tools and tutorials for setting up fake base stations, e.g., Refs. [1, 2]. The fake base station exploits the radio signal-based base station selection process and the vulnerability in the broadcasting SIB and RRC messages.

Can user equipment evade a fake base station attack after detection?

We also implemented and validated link routing to show that the user equipment can evade a fake base station attack after detection. In the implementation, we showed that our scheme reduces the fake base station availability threat impact from an infinite time duration (without our scheme defense) to only 2.93 2.93 s (with our scheme defense).

Can UE attachments be mitigated against fake base stations?

Unfortunately, this scenario opens new security challenge against Fake base station, in which UEs can be at risk when transferred to these base stations. The aim of this study is to mitigate UE attachments against fake base stations through threshold-based detection and localization.

Does our scheme detect a fake base station?

Against a legitimate base station, our scheme correctly does not detect and blacklist the base station. Against a fake base station persistently withholding the connection, our scheme correctly decides that it is a fake base station, and the false-negative rate is zero.
