Abstract
A user terminal includes a communication circuit, an encryption-decryption circuit, and an execution circuit. The communication circuit receives a core code file of an application from a peripheral device, which stores the core code file of the application, when certifying a core code of the application. The encryption-decryption circuit encrypts the core code file and transmits the encrypted core code file to the peripheral device, and, when executing the application, receives the encrypted core code file from the peripheral device and decrypts the encrypted core code file. The execution circuit executes the application using the decrypted core code file and a normal code file of the application stored in the user terminal. Since the normal code file is stored in the user terminal and the core code file is stored in the peripheral device, the core code of the application is protected from reverse engineering attacks.
