DIGITAL RIGHTS MANAGEMENT OF A DIGITAL DEVICE

摘要

According to one embodiment, an apparatus involves the descrambling of scrambled digital content using a one-time programmable key and digital rights management, the apparatus (110) comprises a processor (360) and a descrambler (380). The processor (360) is adapted to execut a Digital Rights Management (DRM) function (375) in order to determine whether each entitlement needed to access the digital content is pre-stored. The descrambler (380) is adapted to decrypt encrypted information using a Unique key (430) stored within the one-time programmable memory (400). After determining that each entitlement needed to access the digital content is pre-stored, the decrypted information is used to generate a key, which is used to decrypt at least one service key for descrambling the scrambled digital content.
