Abstract
Methods and apparatus for protecting fixed storage entertainment assets are disclosed. A digital entertainment product stored on a digital media comprises a hub including a smart card storing thereon a certificate or private key and an exterior portion of the digital entertainment product surrounding the hub. The exterior portion stores encrypted digital entertainment content in a read-only format. The smart card is adapted for enabling decryption of the digital entertainment content using the certificate or private key. For instance, when public encryption schemes are desired, the smart card is adapted for accessing a public key and for generating a decryption key from the private key and the public key for decrypting the encrypted digital entertainment content. A player may then use this decryption key for decrypting the encrypted digital entertainment content for presentation to a user.
