    摘要： The invention relates to an apparatus and a method for rendering user data. In order to provide a higher level of protection against hacking of data during transport within a PC, a method is proposed according to the present invention comprising the steps of: - receiving encrypted user data and key data by a drive unit (2), - decrypting said user data using said key data, - re-encrypting said decrypted user data using a re-encryption key, - transmitting said re-encrypted user data and said re-encryption key from said drive unit (2) to an application unit (3), - decrypting said re-encrypted user data using said re-encryption key, - reproducing said decrypted user data into application data, - re-encrypting said application data, - transmitting said re-encrypted application data from said application unit (3) to said drive unit (2), - decrypting encrypted application data, - transmitting said decrypted application data from said drive unit (2) to a render unit (4), and - rendering said application data.

    摘要： A terminal for receiving and re-transmitting information, comprises a first network adapter (31, 36) for receiving a primary data stream in which the information has been encoded, encrypted according to a key scheme from a primary transmitter (25,26,27) through a first network in a first format,
    an arrangement for receiving entitlement messages, enabling an authorised receiver to decrypt the encrypted data stream, and at least one further network adapter (37) for connection to a secondary network (2). The terminal is configured to retransmit at least part of the information in at least one secondary data stream in a second format, differing from the first format, through the second network (2) to at least one secondary terminal (3,5,6) connected to the secondary network (2). The terminal is configured to transmit the secondary data stream(s) encrypted according to the same key scheme and to forward received entitlement messages that enable an authorised receiver to decrypt the secondary data stream(s) to the secondary terminal(s) (3,5,6).
