DATA CARRIER WITH OBSCURED POWER CONSUMPTION |
| 摘要 |
<p>In order to prevent the retrieval of data via the measurement of the power consumption in a data carrier provided with a data processing device, it is proposed to connect a load circuit to the power supply of the data carrier so as to influence the power consumption of the data carrier at least during security-relevant operations of the data processing device.</p> |
