Abstract:
In a key management system, a RFID tag decrypts a first key encrypted by a master key and stores the decrypted first key to a service key storage region, then decrypts a second key encrypted by the first key in a third party server, then, encrypts the decrypted second key by the master key and transmits the second key encrypted by the master key to an application of a mobile information terminal, and then decrypts the encrypted second key returned from the application and stores the decrypted second key to the service key storage region.
