\nLe contr\u00f4le de flux d’information (ou DIFT, pour Dynamic Information Flow Tracking) est une des techniques qui permet de d\u00e9tecter des attaques logicielles en identifiant les comportements anormaux lors de l’ex\u00e9cution d’un programme.
\nPlusieurs impl\u00e9mentations logicielles existent. Elles sont fonctionnelles mais souffrent d’un d\u00e9faut majeur : les surco\u00fbts temporels li\u00e9s au DIFT emp\u00eachent son utilisation dans un contexte temps r\u00e9el.
\nNous verrons dans cette pr\u00e9sentation comme tirer profit de certains composants mat\u00e9riels pr\u00e9sents dans les processeurs ARM pour r\u00e9aliser du contr\u00f4le de flux d’information \u00e0 moindre co\u00fbt temporel mais \u00e9galement sans modification de l’architecture du processeur contrairement \u00e0 certains travaux qui seront pr\u00e9sent\u00e9s.
\nNous verrons \u00e9galement que le SoC (System-on-Chip) que nous utilisons permet d’\u00eatre 90% plus rapides en ce qui concernent les co\u00fbts temporels d’instrumentation ce qui ouvre des perspectives int\u00e9ressantes.<\/p>\n
