Abstract: A fake base station (FBS) redirection attack method using unicast message injection in a long term evolution (LTE) wireless section and a system thereof are provided. The FBS redirection attack method includes synchronizing with a signal of a commercial base station connected with a target device being an attack target, transmitting an international mobile subscriber identity (IMSI) paging message to the target device using an IMSI of the target deice, and injecting a unicast message including a frequency of an FBS into the target device, before a base station re-access process is completed in the target device which decodes the IMSI paging message.

Abstract: Disclosed is a method and system for international mobile equipment identity (IMEI) verification and unauthorized terminal detection based on contents of control plane messages exchanged in a process of a terminal that accesses a commercial network in a mobile communication network and the method includes constructing a fingerprint database for each terminal using contents of a control plane message generated in a process of a terminal that accesses a commercial network and a response to the control plane message; and verifying IMEI for an arbitrary terminal that accesses the commercial network using the fingerprint database.
