摘要

Managing the use of an optical disc drive by a program at high security. An OS of a host apparatus 100 sends one user certificate incorporating the policy information defining the use contents permissible for the optical disc drive 200 and a user key to the optical disc drive 200 under a secure environment (S 3 ). On the other hand, the program running on the OS is authorized, and the user key is passed to the authorized program (S 6 ). The optical disc drive 200 authorizes the program using the user key within the user certificate and the user key for the program and specifies the policy information corresponding to the user key (S 7 ). Thereafter, the optical disc drive 200 permits the application program to gain access to the self-resource within the limits of the contents defined in the policy information (S 8 ).
