Abstract: A method, device and computer program product for securing access to an encoded variable in a computer program with a plurality of encoded variables that each having its own dynamic signature, wherein when the encoded variable is accessed, the dynamic signature of the variable is modified, where the sum value for all dynamic signatures of all other encoded variables is controlled in an encoded tracer variable, the sum value being controlled in the tracer variables is adapted if a dynamic signature of one of the encoded variables is modified, the encoded variable is compared with the sum value stored in the encoded tracer variable to monitor the sum of the dynamic signatures, and where an error handling process is initiated in the event of a discrepancy such that all signatures in an arithmetically encoded program can be managed in a high-performance manner regardless of the complexity of the program.

Abstract: A method, a device and computer program for recording a plurality of events in an encoded tracer variable in a security-oriented computer program, wherein each event is recorded as a value in the encoded tracer variable, where in order to simultaneously record multiple events from the values for the events, a total value is first calculated which is then recorded in the encoded tracer variable, such that multiple independent consistency criteria can be advantageously processed simultaneously to detect and propagate errors or other events and such that by virtue of the simultaneous processing, many dynamic effects are prevented during the detection and propagation of errors/events, thus allowing for the necessary reduced complexity of security programs.

Abstract: The method serves for expanding and formatting profiled metal strip material (1) to form a netting-like mat structure (2) of a predeterminable mesh width by a continuous drawing-open process. For this purpose, the strip material (1) is provided with notches (3), which extend in the longitudinal direction of the strip, are of a limited length and between them form metal strands (11), wherein, after the expanding and formatting, the unnotched regions form netting nodes (4) and initially the metal strands (11) are connected to one another by way of adjoining webs in the base of the notch. The webs have fatigue-fracture induced incipient tears formed by flexural deformation. The remaining web is then severed by a separating roll, so that the metal strands (11) are reliably separated from one another in the notch region and the strip material (1) can be drawn open to form the netting-like structure.
