USER TERMINAL TO PROTECT THE APPLICATION USING PERIPHERALS AUTHENTICATION AND METHOD FOR PROTECTING APPLICATION USING THE SAME

摘要

The present invention relates to a user terminal for protecting an application program by authenticating a peripheral device and a method for protecting an application program using the same. The user terminal according to one embodiment of the present invention includes: a communications unit for installing by downloading a general code of an application program from an application provision server, performing a pairing connection with the peripheral device storing a core code of the application program, receiving a unique information of the peripheral device from the paired peripheral device and thereby transmitting the unique information of the user terminal to the peripheral device; an encryption and decryption unit for encrypting and storing the received unique information of the peripheral device, extracting the unique information of the user terminal, and encrypting thereof; an authentication unit for when the application program is executed, comparing the unique information of the periphery device received from the periphery device and the unique information of an encrypted periphery device stored in the user terminal, authenticating the periphery device using a comparison result, and authenticating the user terminal by comparing the unique information of the user terminal, extracted from the user terminal and unique information of an encrypted user terminal received from the periphery device; and an execution unit for, when the authentication of the periphery device and the user terminal is completed, running the application program by using the general code and the received core code.
