Abstract: A method for determining an error vector for a data word according to a Reed-Muller Code includes determining the syndrome of the error vector according to the Reed-Muller Code, expanding the syndrome with zeroes to 1 bit length less than the length of the Reed-Muller Code, determining a code word of a Simplex Code of 1 bit length less than the length of the Reed-Muller Code whose difference to the expanded syndrome has a weight below a first threshold or equal to or above a second threshold, expanding the difference between the determined code word and the expanded syndrome by a zero, and outputting the expanded difference as error vector if its weight is below the first threshold or outputting the inverted expanded difference as error vector if the weight of the expanded difference is equal to or above the second threshold.

Abstract: A decoder comprises a feedback shift register having a plurality of register elements that implement a simplex code and take a register vector for determining an appropriate syndrome fed into the feedback shift register and stored in the plurality of register elements. A combination device algebraically combines a subset of the register elements and provides a combination result vector. A majority decision-making unit ascertains a most frequently occurring value within the combination result vector and provides it as a decision result. An input selector connects an input of the feedback shift register to an input interface arrangement or to an output of the majority decision-making unit, and provides an input vector by the input interface arrangement and corresponds to the ascertained form of the physical unclonable properties as a register vector and, and provides a decision vector comprising the decision result and further decision results as a register vector.
