Abstract: There is provided a low-resolution imaging apparatus configured to form and transmit a low-resolution image of an object. The low-resolution imaging apparatus includes: a low-resolution camera configured to form the low-resolution image of the object; a microcontroller including an analog-to-digital convertor (ADC) that converts the low-resolution image into a digital image; an energy harvesting module configured to provide power to the low-resolution camera and the microcontroller; and a radio frequency identification (RFID) unit configured to transmit the digital-converted low-resolution image.

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: A modulation scheme conversion device includes: a backscattering tag to which a tag signal is provided; and a tag signal forming unit for forming a tag signal. The modulation scheme conversion device multiplies a radio signal, which has been modulated in a first modulation scheme, and a tag signal, and reconfigures the multiplied signal by using a second modulation scheme, so as to backscatter the reconfigured signal, wherein the reconfiguration is performed in a physical (PHY) layer.

Abstract: A method for detecting a GPS spoofing attack using a difference between output values of a GPS receiver, which is generated due to inaccuracy of a GPS spoofer, and an apparatus therefor are provided. The method includes receiving a GPS signal; and determining the received GPS signal as a GPS satellite signal or a GPS spoofing signal using a learning model learned based on a difference between output values of a GPS receiver. The method further includes labeling and collecting dispersion degree data including a position, a speed, and a time output from the GPS receiver with whether the GPS signal is the GPS satellite signal or the GPS spoofing signal and modeling the learning model using the collected data.
