The invention relates to a portable data carrier (10), particularly a chip card, having a communication interface (11) by means of which an encrypted received data stream can be fed to the data carrier (10) and decoded by means of a decoder (12, 13) of the data carrier (10). The portable data carrier (10) according to the invention comprises a data store (14) for storing the data of the encrypted data stream, from which the encrypted data of the data stream can be fed to the decoder (12, 13) for decoding by means of decryption information stored on the data carrier (1), wherein said information can be fed by means of the communication interface (11) to a processing unit (20) checked as authorized by the data carrier (10) by means of the decryption information. |
