  • METHOD AND SYSTEM FOR OBFUSCATING A GRYPTOGRAPHIC FUNCTION
    Publication number: 20090313480
    Abstract: A method of proctecting an integrity of a data processing system. The method comprises determining a data string to be protected, an integrity of the data string being an indication of the integrity of the data protecessing system. Computing 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 the system to process data according to the set of parameters. The set of parameters represents at least part of cryptographic algorithm key. The set of parameters represents a netword 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.
