Abstract
The present disclosure relates to a method for updating a firmware component of a measurement and control technology device. The method includes: a segment-by-segment reception of a first firmware image; an authentication of the first firmware image based upon a first encryption method; a creation of a second authentication datum for the first firmware image via an algorithm that differs from the first encryption method; a re-transmission of the data used for updating the firmware component as a second firmware image; an authentication of the second-firmware image based upon the second authentication datum; and in the case of a successful authentication of the second firmware image, enabling and execution of the firmware program code.
