| Zusammenfassung: | A content distribution system includes a data processing apparatus of a user for receiving a content supplied from a content transmitter, a data processing apparatus of a third party trusted by both the content transmitter and the user, and a communications network connecting the data processing apparatuses of the user and the third party for mutual data communication. The data processing apparatus of the user is provided with a tamper-resistant device storing data inaccessible from outside. The data processing apparatus of the third party transmits first data to the data processing apparatus of the user, wherein the first data relates to an encryption key that decodes a cipher generated by the content transmitter. The encryption key is obtained only within the tamper-resistant device. The tamper-resistant device decodes the cipher by using the first data from the data processing apparatus of the third party. |
