Title
(EN) SECURITY PROCESSOR WITH BUS CONFIGURATION
(FR) PROCESSEUR DE SECURITE A CONFIGURATION DE BUS
Abstract
(EN)
A security subsystem controls the data transfer rights among components of a secured system via a common bus. The security subsystem includes a secure block that is coupled to an access controller, preferably via a hard-wired connection to the controller. This secure block exclusively controls the access rights among components, and can effectively isolate security functions and data from the main processor. Because the security is provided via access control to components or subsets of components via a common bus, an efficient and effective integration of the security subsystem within the secured system can be achieved.
(FR)
Un sous-système de sécurité contrôle les droits de transfert de données parmi les composants d'un système sécurisé au moyen d'un bus commun. Ce sous-système de sécurité comporte un bloc sécurisé couplé à un dispositif de contrôle d'accès, de préférence au moyen d'une connexion câblée avec le dispositif de contrôle. Ce bloc sécurisé contrôle exclusivement les droits d'accès des composants, et il peut efficacement extraire des fonctions de sécurité et des données de sécurité du processeur principal. La sécurité étant assurée par un contrôle d'accès pour les composants ou les sous-ensembles de composants au moyen d'un bus commun, le sous-système de sécurité peut être efficacement intégré dans le système sécurisé.
