Summary: | The invention is concerned with a control device (11) comprising a processor circuit (14) for executing applications (15) that use a cryptographic service functions (24) by calling a respective programming interface (30) of the service function (24), wherein the processor circuit (14) is adapted to execute the respective application (15) as a process (32) of the processor circuit (14). According to the invention, the control device (11) comprises a trusted environment hardware module (23) and an interface module (36) is provided that comprises the programming interfaces (30) for calling the service functions (24) and that is adapted to call one of the following implementations of the service function (24) depending on which service function (24) the respective programming interface (30) belongs to: a local implementation (37) that is executable as a part of the process (32) of the calling application (15) or in a parallel process (32) of the processor circuit (14), or an external implementation (38) that is provided by the hardware module (23).
L'invention concerne un dispositif de commande (11) comprenant un circuit de processeur (14) pour exécuter des applications (15) qui utilisent des fonctions de service cryptographique (24) par appel d'une interface de programmation (30) respective de la fonction de service (24), le circuit de processeur (14) étant conçu pour exécuter l'application (15) respective en tant que processus (32) du circuit de processeur (14). Selon l'invention, le dispositif de commande (11) comprend un module matériel d'environnement de confiance (23) et un module d'interface (36) qui comprend les interfaces de programmation (30) pour appeler les fonctions de service (24) et qui est conçu pour appeler l'une des mises en œuvre suivantes de la fonction de service (24) en fonction de la fonction de service (24) à laquelle appartient l'interface de programmation respective (30) : une mise en œuvre locale (37) qui peut être exécutée en tant que partie du processus (32) de l'application (15) appelante ou dans un processus (32) parallèle du circuit processeur (14), ou une mise en œuvre externe (38) qui est fournie par le module matériel (23). |
