摘要： The present invention relates to digital rights management (DRM) for content that downloaded and saved to a storage device. The storage may be a disk drive, or network attached storage. In addition, the storage device performs cryptographic operations and provides a root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. The binding key is not stored on the storage device with the content. The content key is a key that has been assigned to the content. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is provisioned based on the access key and stored in encrypted form in the storage device.

摘要： The present invention relates to digital rights management (DRM) for content that may be downloaded and bound to a storage device. The storage device may be an intelligent storage device, such as a disk drive, or network attached storage. In addition, the storage device is capable of performing cryptographic operations and providing a root of trust. In one embodiment, the DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. However, the binding key is not stored on the storage with the content. The content key is a key that has been assigned to the content, for example, by a trusted third party. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is encrypted based on the access key and stored in encrypted form in the storage device.

摘要： Data storage devices are provided according to various embodiments of the present invention. In one embodiment, a data storage device comprises a host interface, a buffer, a storage media interface, and a data manipulation engine. The data manipulation engine comprises a receive pipe configured to read first and second data blocks from first and second locations in the buffer and to check the validity of the first and second data blocks, an arithmetic logic unit configured to perform a logic operation on first and second user data of the first and second data blocks, respectively, to generate third user data, and a transmit pipe configured to receive the third user data from the arithmetic logic unit, to generate and append a third checksum to the third user data to produce a third data block, and to write the third data block to a third location in the buffer.
