Software Update Device And Software Update Program

Abstract: The purpose of the present invention is to enable software to be updated safely in cases when a volatile memory serving as a working area is not sufficiently large. Accordingly an integrated device sequentially performs verification processing with respect to each of a plurality of sections into which update data for updating software has been divided. The integrated device stores intermediate values obtained midway through the verification processing. When the verification processing for all of the sections is complete the integrated device compares the values obtained by the verification processing with verification data to ascertain that there has been no modification. When it can be determined that there has been no modification the integrated device sequentially performs verification processing with respect to each of the sections again. The integrated device compares the intermediate values obtained by the verification processing with the stored intermediate values and when said values match uses the sections to update the software.
