1. A method for checking a processing of payload data, comprising the following steps:
ascertaining respective reference result data for each admissible sequence of data processing blocks of multiple admissible sequences of data processing blocks that result when predetermined meta data are processed by the admissible sequence of data processing blocks in the order of the admissible sequence of data processing blocks;
receiving, by a control device including a processor, payload data result data and meta data result data for a data processing of the payload data and the meta data;
checking whether the meta data result data received by the control device agrees with the respective reference result data ascertained for at least one admissible sequence of data processing blocks of the multiple admissible sequences of data processing blocks; and
triggering a safety measure when the meta data result data received by the control device does not agree with the respective reference result data ascertained for any admissible sequence of data processing blocks of the multiple admissible sequences of data processing blocks.
