Abstract: An encryption method is provided that has a software model of a technical system, the model including software components is encrypted by a public key and a decryption structure, wherein the latter includes definitions of component groups of the software model. The decryption structure is integrated at least partially into the encrypted software model. Correspondingly, in a decryption method according to the invention, via a secret key that likewise comprises definitions of component groups, only the particular component groups are decrypted whose definitions the secret key includes in agreement with the definitions of the encrypted software model. The definitions of the secret key can be extended after the fact by a key extension, so that additional component groups can be decrypted with an extended secret key.

Abstract: A test device for testing at least a portion of a virtual control unit with a simulation environment in a simulator, having the virtual control unit and the simulation environment. The virtual control unit has at least one software component with an external data interface. The simulation environment has a data interface for indirect data exchange with the virtual electronic control unit. A reduced dependency between the virtual control unit and the simulation environment with the result that electrical fault simulation with virtual electronic control units is possible in a simpler way, is achieved in that a virtual control unit pin module and a virtual manipulation unit are additionally provided between the virtual control unit and the simulation environment, the two units transmit a virtual physical control unit signal through a virtual control unit pin of the virtual electronic control unit pin module. The virtual manipulation unit outputs a manipulated virtual physical control unit signal.

Abstract: A test device for testing at least a portion of a virtual electronic control unit with a simulation environment in a simulator, having the virtual electronic control unit and the simulation environment. The virtual electronic control unit has a software component with an external data interface. The simulation environment has a data interface for direct data exchange with the virtual electronic control unit. A test device with reduced adaptation effort is implemented via a virtual electronic control unit pin module that has at least one virtual electronic control unit interface and is connected via the virtual electronic control unit interface to the external data interface of the software component of the virtual electronic control unit.
