Abstract: An integrated circuit chip stack includes a main integrated circuit chip and at least one auxiliary integrated circuit chip. The main integrated circuit chip contains circuit components to be protected. The auxiliary integrated circuit chip is mounted to a surface of the main integrated circuit chip and includes a metal plane connected to ground located opposite the circuit components to be protected. The auxiliary integrated circuit chip further includes at least one insulated conductive track forming a tight pattern opposite the circuit components to be protected. A detection circuit is connected to the at least one conductive track and is configured to detect interruption of the at least one insulated conductive track.

Abstract: A circuit module of an integrated circuit is located in a first zone of a semiconductor substrate. A decoy cell includes an antenna above a second zone of the semiconductor substrate. The second zone is different from the first zone. A generation circuit operates to generate a decoy electrical signal on the basis of a first electrical signal that is characteristic of an operation of the circuit module and of at least one pseudo-random parameter. The decoy electrical signal is circulated through the antenna so as to generate a decoy electromagnetic radiation.
