Abstract: Disclosed herein are an apparatus and method for calculating a multiplicative inverse. The apparatus for calculating a multiplicative inverse includes a data input unit for receiving input data, a multiplicative inverse calculation unit for dividing an input degree-8 finite field corresponding to the input data into two first degree-4 finite fields so as to perform Advanced Encryption Standard (AES) encryption on the input data, and for performing a multiplicative inverse calculation on the first degree-4 finite fields in consideration of a circuit depth value (T-Depth) and qubit consumption of quantum gates in a quantum circuit, and a data output unit for outputting result data obtained by performing the multiplicative inverse calculation.

Abstract: An apparatus and method for collecting the radio frequency (RF) feature of a wireless device in a wireless communication apparatus are disclosed herein. The RF feature extraction unit adds a tag having a unique value to a received radio signal, and extracts RF feature information from the radio signal. The MAC information extraction unit extracts the source MAC address and tag information of a MAC protocol frame from the received radio signal, and then removes the added tag. The tag comparison unit selects an source MAC address and RF feature information, when the tags have the same value, from the RF feature information and tag information from the RF feature extraction unit and the source MAC address and tag information from the MAC information extraction unit. The RF feature storage unit stores the selected source MAC address and RF feature information.

Abstract: An apparatus and a method for identifying a rogue device having a media access control (MAC) address counterfeited/forged when a wireless intrusion prevention system controls an access to an access point (AP) and a wireless terminal which are not applied are disclosed. The apparatus includes: a sensor unit configured to collect MAC addresses, RSSI values, and RF feature values based on RF signals of wireless terminals; an RF feature database configured to store the collected MAC addresses, RSSI values, and RF feature values; and a terminal identification unit configured to identify whether a MAC of any one of the wireless terminals is forged by comparing information of the RF feature database with the RSSI value and the RF feature value of any one of the wireless terminals according to a MAC verification request of any one of the wireless terminals from the sensor unit.
