Abstract
A method for installing embedded firmware is provided. The method includes generating one or more firmware file instances and generating one or more digital certificate instances that are separate instances from the firmware file instances. The method includes associating the one or more digital certificate instances with the one or more firmware file instances to facilitate updating signature-unaware modules with signature-aware firmware or to facilitate updating signature-aware modules with signature-unaware firmware.

12. A software tool for generating firmware signatures, comprising:
-
a code generator to produce one or more binary file instances; a certificate component to generate one or more digital certificate instances that are separate instances from the binary file instances, where at least one digital certificate instance is generated for each binary file instance generated; and a platform component to link the one or more digital certificate instances with the one or more firmware file instances to facilitate updating industrial control module firmware in a secure manner. - View Dependent Claims (13, 14, 15, 16, 17, 18)
