US Patent 7464408 Damage containment by translation

Interface elements of a logic module are translated by renaming, adding dummy elements, and/or associating traps with dummy elements. Trusted parties are made aware of renamed interface elements and thereby allowed to properly communicate with logic module. Untrusted parties are kept unaware of the interface translation, with attempts to guess correct interface elements likely to fail, instead resulting in communication attempts with dummy elements and subsequent trapping of the untrusted parties.
