| 摘要 |
<p>A recorder consists of a drive (102) and a host (103) performing mutual authentication. C2_G (141) of the drive (102) is transferred to the host (103) after a medium unique key calculated by the medium ID and a medium key is encrypted by using a session key (Ks) generated by mutual authentication. A title key generated by a random number generator (143) of the drive (102) is transferred to the host (103). C2_G (145) of the drive (102) is transferred to the host (103) after the content key calculated from the title key and the CCI (232) is encrypted by using the session key (Ks). By using the content key decrypted by the host (103), the content is encrypted and the drive (102) records the encrypted content, encryption title key, and the CCI (232) onto a medium (101).</p> |
