<p>The arrangement has a shield (1) at least partly covering the IC (13), a signal transmitter (2), a signal receiver (3), conductors (4, 5) between them, a control and evaluation device (8) for the transmitter and receiver and a covering on the substrate. The shield has a switching device (6) enabling capacitive measurement in one setting and enabling detection of shield damage in another setting. Independent claims are also included for the following: (a) a method of protecting an IC against reverse engineering.</p> |
