Abstract: A method for processing an operating sequence of instructions of a program in a processor, wherein each instruction is represented by an assigned instruction code which comprises one execution step to be processed by the processor or a plurality of execution steps to be processed successively by the processor, includes determining an actual signature value assigned to a current execution step of the execution steps of the instruction code representing the instruction of the operating sequence; determining, in a manner dependent on an address value, a desired signature value assigned to the current execution step; and if the actual signature value does not correspond to the desired signature value, omitting at least one execution step directly available for execution and/or an execution step indirectly available for execution.

Abstract: A method for correcting a data block comprises applying a first error correction and error detection in accordance with a first code to a first set of vectors of a data block, wherein the first code makes it possible to detect vectors having a number of errors above a maximum number as erroneous but uncorrectable, but only to correct vectors having a number of errors up to the maximum number, and applying a second error correction and error detection in accordance with a second code to at least some of a second set of vectors, wherein, if error correction of a vector of the second set causes the first error correction and error detection, for a vector of the first set that it detected as erroneous but uncorrectable, indicate fewer errors than the maximum number, error correction of the vector of the second set is revoked.

Abstract: One exemplary embodiment describes an electronic data processing device comprising a memory configured to store encrypted program code for a cryptographic algorithm, a cryptoprocessor unit having a security processor, an interface to the memory, an internal volatile memory and a crypto function circuit, a data processing circuit having an interface to the cryptoprocessor unit, and a path selection circuit which is configured, in a configuration state, to provide a first data path from the memory, via the crypto function circuit, to the internal volatile memory of the cryptoprocessor unit and, in an execution state, to interrupt the first data path and to provide a second data path between the security processor and the internal volatile memory and the crypto function circuit.

Abstract: According to one embodiment, an integrated electronic circuit has a switching network configured to receive binary control states, one or more secret-carrying gates, wherein each secret-carrying gate represents Boolean secrets and is configured to receive binary input states and to output one or more Boolean secrets according to a state sequence of the binary input states, and one or more flip-flops configured to store binary output states output by the switching network and to supply binary input states to the one or more secret-carrying gates based on the stored binary output states. The switching network generates the binary output states by combining the binary control states and Boolean secrets output by the one or more secret-carrying gates. The integrated electronic circuit outputs Boolean secrets from the one or more secret-carrying gates and/or the binary output states from the switching network to another integrated electronic circuit.

Abstract: A method for reconstructing a physically unclonable function (PUF) A for use in an electronic appliance is provided. The method includes producing a checksum C, producing a defective PUF B and reconstructing the PUF A from the defective PUF B using an error correction algorithm. The algorithm produces a plurality of ambiguous results (A1, A2, . . . , An) for the PUF A in a fraction of the cases and a single result, which may be incorrect, in all other cases. The method also includes determining by means of the checksum C which of the plurality of ambiguous results (A1, A2, . . . , An) is the correct PUF A or of whether a single result corresponds to the correct PUF A.

Abstract: A consumer device is described, comprising a sensor which is adapted to register sensor data that describe a physical behavior of an authentication chip of a consumable component, an authentication circuit which is adapted to implement a machine learning model that is trained to classify consumable components with the aid of sensor data that describe the physical behavior of authentication chips of the consumable components into originals and copies, to deliver the registered sensor data to the machine learning model, and to authorize the use of the consumable component by the consumer device depending on whether the machine learning model classifies the consumable component as original.
