A method for checking a processing of payload data. The method includes processing the payload data and metadata by a sequence of data processing blocks. An adjustment value is ascertained for each data processing block as a function of a thereto-supplied payload data version so that, if the thereto-supplied metadata version is correctly processed by the data processing block to form a respective processing result, the processing result, after having been adjusted according to the adjustment value according to a specified adjustment rule, is equal to a value assigned to the data processing block. Each data processing block processes the metadata version supplied to it, and the next metadata version is derived from the supplied metadata version as a function of the processing result adjusted according to the adjustment value according to the specified adjustment rule, and checking whether the payload data have been processed correctly.
