Abstract: A digital rights management (DRM) system operates on a computing device when a user requests that an encrypted piece of digital content be rendered by the computer device. The computing device has an identifier. A black box performs decryption and encryption functions in the DRM system. The black box includes a key file and an executable. The key file includes at least one black box public key and is expected to include the identifier of the computing device, the black box thus being tied to the computing device by inclusion of such first identifier. A digital license corresponding to the digital content is resident in the DRM system and includes a decryption key for decrypting the encrypted digital content. The decryption key is expected to be encrypted according to a black box public key of the key file of the black box, the license thus being tied to the black box and by extension the computing device.
