Zusammenfassung:	A method of protecting an integrity of a data processing system. The method comprises determining (902) a data string to be protected, an integrity of the data string being an indication of the integrity of the data processing system. Computing (904) a set of parameters representing a predetermined data processing function, using a redundancy in the set of parameters to incorporate the data string into a bit representation of the set of parameters. Enabling (906) the system to process data according to the set of parameters. The set of parameters represents at least part of a cryptographic algorithm including a cryptographic key. The set of parameters represents a network of look-up tables. The network of look-up tables comprises a plurality of look-up tables of a white-box implementation of a data processing algorithm. The data processing algorithm comprises a cryptographic algorithm.
