1. A method comprising:

  • manufacturing field programmable gate array integrated circuits, each integrated circuit having an identification code and a secret cryptographic key; and

    creating a database of identification codes and secret cryptographic keys, wherein a field programmable gate array integrated circuit with a particular identification code is configurable using a bitstream encrypted using a secret cryptographic key associated with the particular identification code;

    wherein the encrypted bitstream configures the field programmable gate array integrated circuit with the particular identification code by programming a plurality of electrical switches in the field programmable gate array integrated circuit to create a circuit corresponding to a user design.
