摘要： A method, device and system for controlling JTAG interface enablement within a communication device. The JTAG interface can be selectively enabled based on the receipt of an encrypted access token generated by an access token server. The access token server generates the access token in response to an end user providing appropriate device-specific information. The access token includes appropriate information that, upon appropriate authentication and decryption, can temporarily device bind the boot code image of the device in a manner that enables the JTAG interface. Alternatively, the access token includes appropriate information that instructs the general purpose processor to choose between JTAG interface enablement information and JTAG interface disablement information for use with the boot code image of the device. The access token can include expiration information that causes an enabled JTAG interface to revert back to its disabled status upon expiration of the access token.

摘要： A process may be utilized by a DVR. The process characterizes a set of content as a plurality of segments as the set of content is received. Each of the segments has a segment length according to a predetermined time interval. Further, the process encrypts each of the segments with a corresponding content encryption key to generate a plurality of encrypted segments. The corresponding content encryption key for each of the segments is generated by the DRM component. In addition, the process stores each of the encrypted segments for playback with trick play features in accordance with an expiration content rule having a time limit on the temporary playability of the set of content.

摘要： The present invention discloses an apparatus and method for a method for determining proximity of a device (e.g., a client device). In one example, a key management request is acquired from the device. A measurement request is then transmitted to the device. Afterwards, a measurement reply is received from the device. In response, a determination is made as to whether a measurement parameter associated with the transmitting and the receiving exceeds a predetermined threshold. If the predetermined threshold is not exceeded (i.e., the device is proximate to an associated local network), then a reply to the original key management request is transmitted to the device. Notably, the reply to the key management request is required for the device to establish a secure session with a server from which digital content can be acquired.

摘要： A digital rights management architecture for securely delivering content to authorized consumers. The architecture includes a content provider and a consumer system for requesting content from the content provider. The content provider generates a session rights object having purchase options selected by the consumer. A KDC thereafter provides authorization data to the consumer system. Also, a caching server is provided for comparing the purchase options with the authorization data. The caching server forwards the requested content to the consumer system if the purchase options match the authorization data. Note that the caching server employs real time streaming for securely forwarding the encrypted content, and the requested content is encrypted for forwarding to the consumer system. Further, the caching server and the consumer system exchange encrypted control messages (and authenticated) for supporting transfer of the requested content. In this manner, all interfaces between components are protected by encryption and/authenticated.

摘要： In a method for communicating media content stored on a digital video recorder (DVR) protected by a first DRM system to a portable multimedia device (PMD) using a second DRM system, in which the first DRM system differs from the second DRM system, a request for communication of a media content item stored on the DVR to the PMD is received. In addition, a portable content key is employed to encrypt the media content item to a PMD format suitable content version and the encrypted PMD format suitable content version is communicated to the PMD along with a portable content identifier (ID).
