摘要： A semiconductor integrated circuit for the processing of conditional access television signals that includes an input interface for receiving encrypted television signals and an output interface for output of decrypted television signals. The semiconductor integrated circuit is provided with some functionality restricted in some way by preventing one or more hardware circuit elements from operating, such as an MPEG decoder, display engine, IO ports or main CPU. To enable the functionality, a subscriber must pay for a service and then receives an encrypted message broadcast to the semiconductor integrated circuit that is decrypted and instructs functionality to be turned on or off.

摘要： Provided is a migration system considering security authentication levels and data protection strength levels of the both security devices between which data is migrated. A first terminal 102 includes a mechanism for protecting data by a private key in the public key method held by TPM, and a second terminal 103 includes a key in the private key method encrypted by the private key in the public key method held by TPM and a mechanism for protecting the data by the key. A Migration Authority 101 holds a security policy table describing a security policy and judges whether data movement from the first terminal 102 to the second terminal 103 is enabled according to the security policy table.

摘要： A method and apparatus for brokering the enablement of the communication of encrypted media programs from a plurality of independent broadcasters to a plurality of receivers is disclosed. The system makes use of a pairing key for each provided service, which is differently encrypted by a pairing server and by the broadcaster providing the service. The encrypted versions of the pairing key are decrypted in a first receiver module using information known to the pairing service but not the broadcaster and in a second receiver module using information known to the broadcaster. The pairing key is used to cryptographically bind the first and second receiver modules.

摘要： A content reception equipment for accessing an in-home content transmission equipment from a remote place executes a first authentication process with the content transmission equipment in advance, executes the remote access information sharing process required for access from a remote place, and causes the information on the content reception equipment and the remote access information to be registered in an equipment information table of the content transmission equipment. In the case where the in-home content transmission equipment is accessed by the content reception equipment brought out of home, the content transmission equipment transmits the content to the content reception equipment only in the case where the information on the content reception equipment is registered in the device information table of the content transmission equipment and the second authentication process using the remote access information is successfully executed between the content transmission equipment and the content reception equipment.
