1. A method of configuring a field-programmable gate array (FPGA), the method comprising:

  • receiving, at an FPGA, an encrypted FPGA load-decryption key from a remote key-storage device, wherein the remote key-storage device is external to and operatively connected with the FPGA;

    decrypting the encrypted FPGA load-decryption key in a key-security unit to provide a decrypted FPGA load-decryption key;

    receiving encrypted FPGA-configuration data at the FPGA; and

    decrypting and authenticating, in a configuration-data security unit, the FPGA-configuration data using the decrypted FPGA load-decryption key.
