Abstract:
A method for authenticating a piece of firmware to be downloaded to a controller. The method includes signing the firmware or a first part of the firmware with a first private key at a first trusted source and signing the firmware or a second part of the firmware with a second private key at a second trusted source. The method also includes validating the signed firmware or the first part of the firmware using a first public key at the controller and validating the firmware or the second part of the firmware using a second public key at the controller. The method further includes authenticating the firmware if the firmware or the first part of the firmware is validated by the first public key at the controller and the firmware or the second part of the firmware is validated by the second public key at the controller.
