Abstract
A device such as a mobile receiving unit (28) may include a memory (74) having a software image (106) therein. The memory (74) has a first stored signature (104) therein. A controller (60) may include a boot loader module (69) that generates a second signature from a portion of the software image (102A-E) less than a full image. The controller (60) authenticates the software image using the first signature and the second signature.
