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.
