Abstract (en)
[origin: WO2005002132A2] The invention relates to a portable data carrier (1) for decoding cryptographically secured digital data representing a digitalisation of an analog signal. The inventive portable data carrier (1) is characterised in that it is provided with a decoding function (2) for decoding the cryptographically secured digital data, and has a digital-analog converter (3) for converting the decoded digital data into the corresponding analog signal.
