Patent

CA 2690095

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.

L'invention concerne un procédé et un système mis en oeuvre par ordinateur permettant d'intégrer et d'authentifier des informations auxiliaires dans un contenu signé numériquement. Ce procédé et ce système consistent à charger un contenu numérique qui contient un exécutable signé numériquement dans une mémoire pour exécution, tout en vérifiant l'intégrité de la signature numérique et le contenu de l'exécutable; et à effacer toutes les régions non authentifiées du contenu numérique par annulation ou par remplissage de valeurs dans les zones de mémoire correspondant aux régions non authentifiées.
