Mechanisms are disclosed that allow for execution of unsigned content and the securing of resources in a closed system when such unsigned content is executing on the system. For example, an access layer is used between an operating system layer of the closed system and the actual unsigned content. This access layer may contain various sub-layers, such as a graphics layer, an audio layer, an input layer, and a storage layer. These layers can control access that the unsigned content can have to the native operating system layers and the associated resources of the closed system. By providing such an access layer, unsigned content, e.g., video games, can run on the closed system that is typically designed to run only signed content.

La présente invention concerne des mécanismes permettant l'exécution de contenu non signé et la sécurisation de ressources dans un système fermé lors de l'exécution d'un tel contenu non signé sur le système. Par exemple, une couche d'accès est utilisée entre une couche de système d'exploitation du système fermé et le contenu non signé réel. Cette couche d'accès contient diverses sous-couches, telles qu'une couche graphique, une couche audio, une couche d'entrée, et une couche de stockage. Ces couches peuvent commander l'accès que peut avoir que le contenu non signé aux couches du système d'exploitation natives et aux ressources associées du système fermé. Grâce à la fourniture d'une telle couche d'accès, un contenu non signé, par exemple, des jeux vidéo, peut être exécuté sur le système fermé qui est typiquement destiné à exécuter uniquement un contenu non signé.
