Abstract: The copy protection system is a combination of a signature method and a coding or encryption method that uses a variable key. The data set is written only onto a predetermined device and it is released to a host for reading and deciphering only upon proper authorization. Copying of the encrypted data set is entirely useless, because the dataset is signed with a unique identification (e.g. the serial number) of the device.

Abstract: A semiconductor configuration includes at least one semiconductor chip having a first chip side, a second chip side, and connections passing through the at least one semiconductor chip, active structures on the first chip side and the second chip side, the connections electrically connecting the active structures to one another, a support having a first support side, a second support side, plated-through holes, and non-conducting regions running alternately with regular spacings from the first support side to the second support side, the plated-through holes spaced apart from one another to define a hole spacing distance between the holes, contact connections connecting the second chip side to the first support side, the contact connections spaced apart from one another to define a connection spacing distance between the contact connections, and the hole spacing distance being smaller than the connection spacing distance.

Abstract: An integrated circuit with at least one antenna for the contactless transmission of data or energy. The antenna is configured above and/or below circuit sections to be protected and, as part of a protective circuit, enables the integrated circuit to be monitored with regard to an undesirable external attack. Such an attack can be identified by the attempt to effect observation or manipulation from the outside, which are typically associated with an alteration of the physical properties of the antenna. These physical alterations lead to significant changes in the protective circuit signals that are transmitted via the antenna. These changes are identified by signal detectors and initiate a transfer of the integrated circuit into a security mode. In this case, in addition to the function as means for transmitting data and/or energy, the antenna also serves the function of being a protective shield of a protective circuit for the integrated circuit.

Abstract: A semiconductor chip having circuits which are produced in at least one layer of a semiconductor substrate and are arranged in at least one group. The semiconductor chip has at least one conductive protective layer which is arranged above at least one such circuit group and is electrically connected to at least one of the circuits. The substrate has at least one protective sensor, and the detection connection(s) of the protective sensor/protective sensors is/are connected to the conductive protective layer or to at least one of the conductive protective layers. Output connections of the protective sensor/protective sensors are connected to at least one of the circuits such that the circuit(s) cannot operate properly if there is a defined, nonvolatile level at the output of the protective sensor(s).

Abstract: A circuit configuration with a deactivatable scan path, includes a number of function blocks each connected to at least one other of the function blocks. At least one sub-set of the connections is in the form of a respective interlocking element which can be switched through an activation line (Scan Enable) from a normal mode to a test mode and which has a further data input and data output. The further data inputs and outputs are connected to one another by data line sections in such a manner that the interlocking elements form a shift register which provides a scan path. At least one electrically programmable protection element, which either interrupts a given line or connects it to a defined potential, is disposed along the activation line (Scan Enable) and/or the data line sections.

Abstract: The power supply device has a temporary energy store, a main energy store, and a switching device. The switching device has three switching states. The temporary energy store is connected in the first switching state to a power supply input and is connected in the second switching state to the main energy store, which is connected to a power supply output. An energy discharge device is connected to the temporary energy store in the third switching state of the switching device which follows directly the second switching state.
