Abstract

In order to further develop a circuit arrangement (100), in particular an active shield, as well as a method for identifying at least one attack on the circuit arrangement (100), wherein test data are generated, the test data are transmitted via at least one group of data lines (50) being designed for carrying data signals in the form of regular data and / or in the form of the test data, the transmitted test data are received, the received test data are compared with expected test data, and any discrepancy between the received test data and the expected test data is ascertained or determined, in such way that less power is required for examining, in particular for identifying, if the circuit arrangement (100) has been attacked, it is proposed that part of the group of data lines (50) is selected to carry new or most recent test data having been generated.

Description

technical field [0001] The invention relates to a circuit arrangement, in particular to an active shield according to the preamble of claim 1 . [0002] The invention also relates to a microcontroller, in particular to an embedded safety controller comprising such a circuit arrangement. [0003] The invention also relates to a digital processing device, in particular to an embedded system, such as a chip card or a smart card, comprising such a circuit arrangement. [0004] The invention also relates to a method for identifying at least one attack on at least one circuit arrangement, in particular at least one attack on at least one active shield, according to the preamble of claim 7 . Background technique [0005] In integrated circuits, the actual semiconductor components are arranged on the lower plane, the so-called active plane, while the wiring of the semiconductor components takes place on the upper plane, the so-called metal plane. Depending on the complexity of the...
