Abstract:
Provided are a method and apparatus for creating and applying a secure file identifier of a rights object by using random numbers. The apparatus includes a secure-file-identifier generating unit which creates the secure file identifier by generating a random number and combining the random number with a hash value corresponding to a rights object identifier of the file identifier list; a transmitting unit which transmits the secure file identifier to the storage device; and a receiving unit which receives a secure file identifier list for identifying the rights object from a storage device.
