Abstract
A secure key generating apparatus comprising an ID calculating unit receiving a primitive ID from a first storage device and calculating a first media ID, (a unique identifier of the first storage device), from the first primitive ID; a user authentication information providing unit providing user authentication information for authenticating the current; and a secure key generating unit for generating a first Secure Key using both the first media ID and the first user's authentication information. The Secure Key is used to encrypt/decrypt content stored in the first storage device. The secure key generating unit generates a first different Secure Key using a second media ID of a second storage device, and generates a second different Secure Key using second user's user authentication information. Only the first Secure Key can be used to decrypt encrypted content stored in the first storage device that was encrypted using the first Secure Key.
