- 論文の詳細を見る
This paper proposes an access control method for composite multimedia content in which only a single key is delivered to a user. The proposed method simultaneously controls access to each medium in one composite multimedia content in which a medium can be hierarchically encoded. This method introduces recursive hash chains for key generation so that the number of delivered key is reduced to one, whereas the conventional method having the above mentioned features has to deliver multiple keys to a user. The managed key in the proposed method is also reduced to one.
