Abstract
System and method for verifying the authenticity of executable images. The system includes a validator that determines a reference digital signature for an executable image using the contents of the executable image excluding those portions of the executable that are fixed-up by a program loader. The validator then subsequent to the loading of the executable image determines an authenticity digital signature to verify that the executable image has not been improperly modified. In addition, the validator ensures that each of the pointers in the executable image have not been improperly redirected.
