    Abstract: An integrated circuit for outputting a function value, comprising a pattern matching circuit, configured to compare an input value and multiple transformed versions of the input value with a specified bit pattern, wherein the transformed versions of the input value or the specified bit pattern are created by repeated application of a transformation to the input value or the specified bit pattern, wherein the function is invariant under the transformation or wherein an inverse transformation exists for the transformation, by means of which a change in the function values that is caused by the transformation of the input values can be reversed, a selection circuit configured to select a function value depending on the matching result of the pattern matching circuit and the input value, and an output circuit configured to output a function value for the input value based on the selected function value.

    Abstract: A method is proposed for copying a source array into a target array, wherein both the source array and the target array have at least two elements, wherein each element has a value, in which the elements of the source array are copied into the target array in the sequence of a random permutation, wherein, after a step of copying an element of the source array into the target array, the source array, the target array or the source array and the target array are rotated. A device is also indicated accordingly.
