ABSTRACT:
Smart (integrated circuit) card supervisory control and data acquisition. Industrial processes may be controlled by one or more smart cards. Signals may be received from an industrial process by the smart card, the signals may be processed by the smart card, and control signals may be sent from the smart card to the industrial process in response to the processed signals. The smart card may provide security/tamper resistance for proprietary information associated with the industrial process. Control of the industrial process may be distributed among one or more smart cards at particular process points to receive sensed process parameters and to send control signals to implement process actions.
