Abstract
Apparatus, method and computer program product are provided for performing integrity checking of a relocated executable module loaded within memory by an operating system loader. A repeatable digital signature is generated by determining the load address of the executable module in memory, normalizing at least some content of the executable module in memory employing the load address of the module, and then performing integrity analysis on a digital section of the module's content, including the normalized content, thereby deriving the repeatable digital signature.
