The invention relates to an integrated circuit, wherein a circuit comprising information to be protected is covered by a screening surface. A network comprising a plurality of nodes is configured in said screening surface. Parts of the nodes are linked to means for a comparison between the desired and the real state. Each node is verified with regard to a characteristic output current using said means. Deviations from the characteristic output current result in a change of the information that is stored in the circuit and that is to be protected against manipulation or analysis. |
