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: Disclosed herein are a finite-field division operator, an elliptic curve cryptosystem having the finite-field division operator, and a method for operating the elliptic curve cryptosystem. The method for operating an elliptic curve cryptosystem may include, setting, by a key setting unit, a length of a key of a cryptographic algorithm, generating, by the key setting unit, first setup information that indicates a number of words corresponding to the key length, and generating, by the key setting unit, second setup information that indicates a number of repetitions of an operation by a finite-field division operator corresponding to the key length.

Abstract: Disclosed herein are a device identification apparatus and method based on network behavior. The device identification apparatus includes one or more processors, and execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to collect packet data of a device connected to a network through port mirroring and extract behavior features from the packet data, analyze the behavior features and then generate unique information based on a previously created detection model, and extract an identification number corresponding to the unique information from a database and then identify the device.

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.
