Zusammenfassung:A circuit for secure operation includes a plurality of mutually exclusive circuit zones including a first circuit zone having a first level of security and a second circuit zone having a second level of security less than the first level of security and one or more gate circuits each providing limited transfer of data between the circuit zones, the gate circuits providing all data connectivity between the first circuit zone and the second circuit zone and statically configured to prevent unmodified transfer of data from the first circuit zone to the second circuit zone.
