Title
(EN) TESTING STORAGE PROTECTION HARDWARE IN SECURE VIRTUAL MACHINE ENVIRONMENT
(FR) TEST DE MATÉRIEL DE PROTECTION DE STOCKAGE DANS UN ENVIRONNEMENT DE MACHINE VIRTUELLE SÉCURISÉE
Abstract
(EN)
A method for testing storage protection hardware includes receiving by a non-trusted entity that is executing on a host server, a request to dispatch a secure entity. It is determined, by a secure interface control of the host server, whether the host server is in an auxiliary-secure (AS) debug mode for testing an AS entity. Based on determining that the host server is in the AS debug mode, a secure guest entity state is loaded from a state descriptor for the secure entity into an AS entity state in hardware to test, upon dispatch of the secure entity, accesses to pages in a memory that are registered as secure and as belonging to the AS entity.

L'invention concerne un procédé de test de matériel de protection de stockage, qui comprend la réception, par une entité ne bénéficiant pas de la confiance s'exécutant sur un serveur hôte, d'une demande de distribution d'une entité sécurisée. Une commande d'interface sécurisée du serveur hôte détermine si le serveur hôte est dans un mode de débogage sécurisé auxiliaire (AS) pour tester une entité AS. Sur la base d'une détermination selon laquelle le serveur hôte est dans le mode de débogage AS, un état d'entité invitée sécurisée est chargé à partir d'un descripteur d'état relatif à l'entité sécurisée dans un état d'entité AS dans un matériel pour tester, suite à la distribution de l'entité sécurisée, des accès à des pages dans une mémoire qui sont inscrites comme sécurisées et comme appartenant à l'entité AS.
