Technical Examples

For cryptographically processing data, data (X) and a key (K) are fed to a cryptographic process (P), which may be a known process. In order to veil the nature of the process (P), auxiliary values as fed to the process, such as a supplementary key (K*), using which a supplementary process (P*) generates the key proper (K). The combination of the original process (P) and the supplementary process (P*) provides an unknown process, hence, the relationship between the supplementary key (K*) and the processed data (Y) is unknown. As a result, improved cryptographic security results.
