Abstract:
A computer-implemented system and method for embedding and authenticating ancillary information in digitally signed content are disclosed. The method and system include loading digital content containing a digitally signed executable into memory for execution, while checking for the integrity of a digital signature and the contents of the executable; and erasing any non-authenticated regions of the digital content by zeroing out or value-filling memory locations corresponding to the non-authenticated regions.
