Abstract: Disclosed herein are a universal subscriber identification module card and a communication method using the same. The universal subscriber identification module card includes a Universal Subscriber Identification Module (USIM) chip, a pad, and a security chip. The USIM chip performs the user authentication of a mobile terminal. The pad electrically connects the USIM chip to the mobile terminal when the USIM chip is inserted into the mobile terminal. The security chip performs a security function for the mobile terminal independently of the USIM chip and shares the two power terminals of the pad with the USIM chip.

Abstract: Disclosed herein are an apparatus and method for detecting a malicious device based on swarm intelligence. The method includes detecting a malicious device by causing at least one exploration ant to access a device swarm along movement routes in which pheromone trail values are taken into consideration, wherein the exploration ant is generated in response to a detection request received from a security management server, when the at least one exploration ant detects a suspicious device that is suspected to be a malicious device, causing the exploration ant to return along the movement routes in reverse order, and returning pheromone trail values generated by devices on the return movement routes to a malicious device detection apparatus, and identifying whether the suspicious device is the malicious device by calculating an optimal solution based on a local information set generated by aggregating the pheromone trail values returned for movement routes.

Abstract: Disclosed herein are a device and method for updating firmware and a firmware update system. The device for updating firmware include an update manager for receiving delta information about the latest version of firmware from an update server by checking information about a version of firmware installed in a terminal device and for updating the firmware installed in the terminal device using the delta information, and a bootloader for restoring the updated firmware using previously stored backup information when the updated firmware is not normally launched or when an error occurs during the update of the firmware.
