| 摘要 |
The invention relates to an electronic device for cryptographic processing, having at least two electronic circuits (IC, CC, CP) coupled via a connection means, wherein the connection means is arranged for transferring data signals between the two electronic circuits. The electronic device further has a monitoring circuit (401) arranged to monitor a deviation in the capacitance of the connection means. In case the deviation exceeds a predetermined value an alert signal (411) is generated.
