    摘要： A method of verification of rights is disclosed, contained in a security module associated to an apparatus processing broadcasted digital data. The apparatus is connected to a management center transmitting encrypted rights messages for accessing the digital data. The method includes reception and reading by the security module of all or part of a rights message including at least one right and means for verifying the right, decryption and verification of the rights message and updating of a rights memory, and storage of all or part of the rights message in a messages memory. During a further verification step, the method includes identification of at least one right present in the rights memory, search of the corresponding stored rights message and verification of the rights message, comparison of the right contained in the rights message with the corresponding right stored in the rights memory, and determination of a default state when the result of the comparison indicates a difference.

    摘要： A method of transmitting and recording digital data scrambled using a control word. The scrambled data is transmitted together with the control word, and the method includes encrypting the control word with a first key. The encrypted control word is transmitted and received, and then decrypted with a decoder that includes an equivalent of the first key. The control word is re-encrypted with a second key stored in a portable support device that is received by the decoder, and the portable support device may be used with any suitable decoder. The re-encrypted control word and the scrambled digital data are recorded on a digital recording medium.An apparatus for transmitting and recording digital data scrambled using a control word. The scrambled data is transmitted together with the control word, and the apparatus includes a transmitter that encrypts the control word with a first key and transmits the encrypted control word. A decoder receives the encrypted control word and decrypts the control word. A portable support device including a second key is received by the decoder, and the decoder uses the second key to re-encrypt the decrypted control word and record the re-encrypted control word and the scrambled digital data on a digital recording medium. The portable support device may be used with any suitable decoder or digital recorder.
