    摘要: A method of generating a Personal Identification Number (PIN) between a first device and a second device in a network is provided. The method includes securely receiving information of input choices of the second device and random numbers assigned to the input choices at the first device. At the first device, the PIN is generated from the random numbers, and instructions are provided directing an entry of the input choices on the second device. At the second device, the input choices are entered. The second device is operable to generate the PIN from the input choices and the random numbers if the input choices are entered as instructed.

    摘要: A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.

    摘要: A system to change security levels is used to change the level of security used in a secured processing system. The system uses a status indicator to designate the security level being implemented. The security level can be upgraded to allow a higher level of security to be implemented with relative ease. However, in order to change from a higher level of security to a lower level of security, an authorization code is utilized to confirm that the change in security is authorized.

    摘要: A secure Internet Protocol (IP) telephony system, apparatus, and methods are disclosed. Communications over an IP telephony system can be secured by securing communications to and from a Cable Telephony Adapter (CTA). The system can include one or more CTAs, network servers, servers configured as signaling controllers, key distribution centers (KDC), and can include gateways that couple the IP telephony system to a Public Switched Telephone Network (PSTN). Each CTA can be configured as secure hardware and can be configured with multiple encryption keys that are used to communicate signaling or bearer channel communications. The KDC can be configured to periodically distribute symmetric encryption keys to secure communications between devices that have been provisioned to operate in the system and signaling controllers. The secure devices, such as the CTA, can communicate with other secure devices by establishing signaling and bearer channels that are encrypted with session specific symmetric keys derived from a symmetric key distributed by a signaling controller.

    摘要: A conditional access subsystem is proved which is to reside with an end-user for receiving, decrypting and decoding all programs distributed by a content provider that the end user is entitled to access so that the decrypted and decoded programs are available for display on one or more display devices without use of a set-top terminal dedicated to each of the display devices. The subsystem includes a receiver for receiving and demodulating a multi-program transport (MPTS) stream distributed by the content provider. The MPTS includes a plurality of packets constituting a plurality of programs using one of N different encryption schemes each associated with one of N service tiers, wherein N is an integer greater than one. Each of the N different encryption schemes has a different encryption/decryption key associated therewith. The packet identifiers for the packets associated with programs in any given one of the service tiers are in a consecutive sequence. A decryptor is provided for decrypting each of the programs associated with each of the N service tiers that the end user is entitled to access. A decoder is also provided for decoding each of the decrypted programs.

    摘要: The present invention discloses an apparatus and method for transferring digital content data. In one example, original digital content data stored on a first device content data. In one example, original digital content data stored on a first device in an encrypted state is transcoded (after being decrypted) to create a modified version of the original digital content data. The modified version of the original digital content data is then encrypted with a new content key. The modified version and at least one content key generator are transferred to a second device, where the at least one content key generator is used to recreate the new content key for enabling (and decrypting) the modified version of the original digital content data at the second device. Notably, the original digital content data stored in the first device is disabled contemporaneously with the transfer of the modified version and the at least one content key generator to the second device. Afterwards, the disabled original digital content data is re-enabled on the first device, and disabled on the second device.
