<p>The microcircuit card (200) has a detecting unit for detecting an attack on the card, and a control unit (130) for generating a control signal (SC) at a high level during normal operation and at a low level when an attack is detected. A combining unit combines the control signal and a vital signal (SIV) of the card to generate a secure vital signal (SIVS). A capacitor (140) is provided for blowing a fuse (250) when the attack is detected, where an inverting gate (260) is connected in series to the fuse.</p> |
