Abstract

Le procédé de partage de temps d'exécution d'un processeur (1) physique entre au moins deux logiciels, ledit processeur comportant un mode d'exécution particulier, dit mode sécurisé, ayant un accès exclusif sur certaines ressources (3, 8, 9), et un premier logiciel, dit de sécurité, étant exécuté exclusivement dans le mode d'exécution sécurisé, et un second logiciel, dit non sûr, étant exécuté dans un mode d'exécution autre que le mode d'exécution sécurisé, est caractérisé en ce qu'il comprend les étapes suivantes : a) on définit un cycle périodique et régulier d'exécution des logiciels par le processeur, b) on découpe ce cycle en deux parties, l'une pour l'exécution du logiciel de sécurité, et l'autre pour l'exécution du logiciel non sûr.
