Abstract
An integrated circuit is protected against at attack. An electrically conductive body at floating potential is situated in the integrated circuit. The electrically conductive body has an initial amount of electric charge prior to the attack and functions to collect electric charge as a result of the attack. A detection circuit operates to detect an amount of electric charge collected on the electrically conductive body and determine whether the collected amount is different from the initial amount. If the detected amount of charge is different from the initial amount, a control circuit trigger the taking of a protective action.
