Self-modifying FPGA for anti-tamper applications
A self-modifying FPGA system includes an FPGA and a configuration memory coupled to the FPGA for providing the FPGA with configuration data including SAFE configuration data and dormant configuration data. The SAFE configuration data is initially loaded to the FPGA and the FPGA is configured to a safe operating mode. Upon a determination to proceed to a next step of self modification, dormant configuration data contained in the configuration memory is loaded into the FPGA and the FPGA is configured to a secure operating mode.
