    摘要: To protect rights of a copyright owner of digital content, technology is required to prevent digital content on a recording medium from being copied onto another recording medium and played back. A key distribution server securely receives a media unique key from a recording medium device, generates a first title key different for each content, encrypts the generated first title key with the media unique key, encrypts the content with the first title key, and transmits the encrypted first title key to the recording medium device and the encrypted content to the recording device. The recording device securely receives the encrypted content from the key distribution server and the first title key and a second title key from the recording medium device, decrypts the encrypted content with the first title key, encrypts the decrypted content with the second title key, and transmits the encrypted content to the recording medium device.

    摘要: A drive device is provided to promote copyright protection by preventing playback of copied contents, even if unique identification information on a recording medium, used to generate title keys for decrypting encrypted contents, is revealed, and the contents are independently encrypted and copied using this identification information. Identification information unique to a recording medium 103 and used to generate title keys is recorded thereon, along with a signature for the identification information issued by a certificate authority terminal device 101. Before decryption and playback of the encrypted contents, a drive in a playback device 104 performs signature verification. When verification fails, the drive does not output the identification information. A program for playback in the playback device 104 therefore cannot generate a decryption key and fails to decrypt and play back the encrypted contents. The signature is not output externally. Therefore, an unauthorized individual cannot copy the recording medium 103.

    摘要: A memory card includes a storage unit storing key information and version information in association with the key information, the key information and the version information being issued by a key issuing authority and the version information indicating a version of the latest revocation list that has been issued when the key information is generated. A revocation list receiving unit receives a revocation list having a version; and a version verification unit compares the version of the revocation list received by the revocation list receiving unit and the version information. When the version of the revocation list is older than version information, processing by a revocation list writing unit is prohibited.
