发明名称 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 comprises a processor and a descrambler. The processor is adapted to execute a Digital Rights Management (DRM) function in order to determine whether each entitlement needed to access the digital content is pre-stored. The descrambler is adapted to decrypt encrypted information using a Unique Key stored within the one-time programmable memory. 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.
