Abstract
According to various embodiments, a circuit for a combined key value-dependent exchange and randomization of two values is described comprising a control input circuit configured to supply two or more shares of a key to an exchange and randomizing circuit, wherein the exchange and randomizing circuit is configured to supply each of the two values to one of two inputs, wherein it depends on at least a first share of the shares which value of the two values is supplied to which input of the two inputs, arithmetically combine, for each of the two inputs, the value supplied to the input with a randomization value to generate a respective randomized value and to store the randomized values in two result locations, wherein it depends on at least a second share of the shares which randomized value is stored into which result location of the two result locations.
