Abstract:
The present invention relates to accessing content stored on a storage device and protecting the content with a digital rights management (DRM) scheme. The storage device may be a disk drive, or network attached storage. The storage device can perform cryptographic operations and provide a hardware root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to the storage device and is based on a key concealed on the storage device. The binding key itself is not stored anywhere on the storage device. The content key is a key assigned to the content. The access key is determined based on a cryptographic combination of the content key and binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.
