    摘要： Basic transfer units (BTUs) of compressed video data of video images are selectively encrypted in accordance with an encryption policy to degrade the video images to at least a virtually useless state, if the selectively encrypted compressed video images were to be rendered without decryption. As a result, degradation that approximates the level provided by the total encryption approach is achieved, but requiring only a fraction of the processor cycle cost required by the total encryption approach, to decrypt and render the video images.

    摘要： A method, apparatus and system enabling software access to navigational data in a decrypted media stream while protecting stream payloads. In one embodiment, a filter may route an encrypted content stream and associated information to a secure partition having a trusted computing component for decryption. Upon decryption, the trusted computing component may store the decrypted payload of the content in a secure storage location accessible to the trusted computing component. Thereafter, the decrypted navigational header information of the content may be used to navigate to the decrypted content via a trusted component such as a trusted rendering unit in the secure partition.

    摘要： A system and method of safeguarding data within a device are described. In one embodiment, at least one protocol specific encrypted data stream is received. The protocol specific encrypted data stream is translated into a protected content exchange (PCX) encrypted data stream. In addition, the PCX encrypted data stream is transferred to a decoding device and the PCX encrypted data stream decrypted.
