Content copying device and content copying method

A content copying device that copies simultaneously in parallel data in a copy source recording medium to a plurality of copy destination recording media, the copy source recording medium having an encrypted content that is a content encrypted with a content key, the content copying device comprising:

• a section that performs a mutual authentication with the copy source recording medium to generate a first medium unique key;
• a first storing section that reads the content key in an encrypted state from the copy source recording medium, decrypts the content key with the first medium unique key, re-encrypts the decrypted content key with a key independent of the recording medium, and stores the re-encrypted content key;
• a second storing section that reads the encrypted content from the copy source recording medium and stores the encrypted content;
• and
• a third storing section that reads information relating to the copy source recording medium, the stored content key and encrypted content, and stores the information as managing information;
• wherein the content copying device is capable of copying, as needed, the same data as in the copy source recording medium to the copy destination recording media using the re-encrypted content key, the encrypted content and the managing information stored in the first to third storing sections.

A content copying method capable of copies simultaneously in parallel data of a copy source recording medium to a plurality of copy destination recording media, the copy source recording medium storing an encrypted content that is a content encrypted with a content key, the content copying method comprising:

• performing a mutual authentication with the copy source recording medium and generating a first medium unique key;
• first storing that includes reading the content key in an encrypted state from the copy source recording medium, decrypting the encrypted content key with the first medium unique key, re-encrypting the decrypted content key with a key independent of the recording medium, and storing the re-encrypted content key;
• second storing that includes reading the encrypted content from the copy source recording medium and storing the encrypted content;
• and
• third storing that includes reading information relating to the copy source recording medium, the stored content key and encrypted content, and storing the information as managing information;
• wherein the content copying method is capable of copying, as needed, the same data as in the copy source recording medium to the copy destination recording medium using the re-encrypted content key, the encrypted content and the managing information stored at the first to third storing steps.
