Method and Systems for Integrity Checking a Set of Signed Data Sections

摘要

Method and systems for integrity checking a set of signed data sections are disclosed. In one embodiment, for each of a plurality of data sections, a digital signature is generated based both on the data for that section and on common data for a set of data sections, even if the common data is stored in another section. The digital signature is stored in that section. For each section, a digital signature is generated based both on the data for that section and on the common data. The generated digital signature is compared with the stored digital signature in that section, and the integrity of the set is verified if the generated digital signature matches the stored digital signature for each section in the set.
