Abstract
An information protection system includes a mobile terminal and an encryption module. The mobile terminal requests a key sequence by transmitting a message including a Personal Identification Number (PIN) number input by a user, and encrypts or decrypts one or more communication signals, including voice signals and data signals, based on the key sequence when the key sequence is received. The encryption module is connected to the mobile terminal. The encryption module encrypts a security key using the identifier and the PIN number of the mobile terminal, decrypts the encrypted security when requested by the mobile terminal, and transmits the key sequence generated based on the decrypted security key to the mobile terminal.
