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.

Abstract: A physical signal overshadowing attack method for an LTE broadcast message and a system thereof are provided. The method includes identifying physical configuration information of user equipment (UE) which is an attack target and manipulating a physical downlink shared channel (PDSCH), a physical downlink control channel (PDCCH), and a physical control format indicator channel (PCFICH) for subframes of the LTE broadcast message transmitted to the UE to form a subframe for attack, synchronizing a time domain and a frequency domain of the subframe for attack depending on the LTE broadcast message, and injecting the synchronized subframe for attack into legitimate subframes of the LTE broadcast message transmitted to the UE and transmitting the injected subframes.

Abstract: Disclosed are an apparatus and method for diagnosing an abnormality of a mobile communication network. The apparatus for diagnosing an abnormality of a mobile communication network includes a modeling unit that models a control plane operation of an analysis target mobile communication network based on a control plane messages collected by a preset Mobile Network Operator to a terminal in a formal model of a form of a state machine, an analysis unit that compares processing required times of a control plane operation model of the modeled analysis target mobile communication network and a control plane operation model of another mobile communication network previously generated in a same path, and a detection unit that detects an abnormal operation of the mobile communication network of the analysis target based on a comparison result.
