Abstract: front page image
(EN)A system (100) comprising a processor (12) adapted to activate multiple security levels for the system and a monitoring device coupled to the processor and employing security rules pertaining to the multiple security levels. The monitoring device restricts usage of the system if the processor activates the security levels in a sequence contrary to the security rules.
(FR)La présente invention concerne un système (100) comportant un processeur (12) apte à l'activation d'une pluralité de niveaux de sécurité pour le système et un dispositif de surveillance couplé au processeur et mettant en oeuvre des règles de sécurité relatives à la pluralité de niveaux de sécurité. Le dispositif de surveillance limite l'utilisation du système si le processeur active les niveaux de sécurité dans une séquence contraire aux règles de sécurité.
