    Abstract: Error correction is proposed, wherein, on the basis of a data word, a syndrome calculation is carried out with a matrix M on the basis of a matrix H of a code, and, if the result of the syndrome calculation reveals that the data word is erroneous, the result of the syndrome calculation is transformed by means of a linear mapping. Next, an error vector is determined on the basis of the result of the linear mapping by means of an efficient error correction algorithm and the erroneous data word is corrected on the basis of the error vector.

    Abstract: A method for evaluating a trustworthiness of sets of a physically unclonable function (PUF) elements, includes: obtaining first information related to a condition of a first set of PUF elements; obtaining second information related to a condition of a second set of PUF elements; and comparing the first information and the second information to determine the trustworthiness of at least one of the sets. The first set includes a first plurality of PUF elements and the second set includes a second plurality of PUF elements. The information related to the condition includes information indicating a respective subset of the set of PUF elements being used or unused when utilizing the respective set of the PUF elements, and/or includes respective error correction information for a bit sequence generated when utilizing the respective set of the PUF.

    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.

    Abstract: A hybrid device includes a plurality of diverse subsystems, including a first and a second subsystem. The first subsystem includes at least one first secured storage device configured to store a first software and a first CPU configured to boot and execute the first software. The second subsystem includes at least one second secured storage device configured to store a second software and a second CPU configured to boot and execute the second software. The first CPU is configured to generate the first hash of the first software and transmit the generated first hash of the first software to the second subsystem. The second CPU is configured to perform a first authenticity validation check on the first software using the received first hash of the first software, and generate an error signal on a condition that the first authenticity validation check on the first software fails.

    Abstract: An apparatus for detecting integrity violation includes a feedback shift register including a plurality of registers connected in series, and a feedback function unit connected between an output of a number of the registers and an input of at least one of the registers. The apparatus further includes an integrity violation detector adapted to determine as to whether a sequence of values at an input or output of at least one of the registers, or a logic combination thereof, is a non-constant sequence or a constant sequence. The apparatus is further adapted to output an indication that the feedback shift register is in an integral state if the sequence of values is a non-constant sequence, or to output an indication that the feedback shift register is subjected to an integrity violation if the sequence of values is a constant sequence.

    Abstract translation: 用于检测完整性违规的装置包括：反馈移位寄存器，包括串联连接的多个寄存器;以及连接在多个寄存器的输出和至少一个寄存器的输入端之间的反馈功能单元。 该装置还包括完整性违反检测器，其适于确定在至少一个寄存器或其逻辑组合的输入或输出处的值序列是非常数序列还是恒定序列。 如果该值序列是非常数序列，则该装置还适于输出反馈移位寄存器处于积分状态的指示，或者如果序列中的序列，输出反馈移位寄存器经受完整性违反的指示 的值是一个常数序列。
