Abstract:
A integrated circuit comprises a circuit part to be protected and protective lines located at least one wiring level of the integrated circuit. In addition, the integrated circuit comprises logical gates coupled to the protective lines, whereby a logic circuit is formed, and a processing unit implemented to detect a manipulation of the integrated circuit by applying test patterns to the logic circuit and verifying a logic output value of the logic circuit responsive to the test patterns.
