Abstract: The invention relates to a method and a secure element for detecting the trustworthiness of an electronic assembly (100). The secure element (200) comprises a control unit (210), a record storage device (230), and a secure storage device (220); the record storage device (230) comprises a target state value (235) of the assembly (100): the secure storage device (220) comprises a private key (226) of a proof of origin (222); the secure element (200) has a public key (224) of the proof of origin (222), said public key being output to a requesting processing unit; and the control unit (210) is designed to carry out the method in order to detect the trustworthiness .

Abstract: A method for controlling a data processing device connected to a computer via an interface wherein a device specific command is generated on the computer by an application program, the command is stored in a special file and is then transmitted by the computer to the device with the aid of a write instruction of the computer operating system. The special file is received by the device, the device specific command is read out from the special file and the device processor executes the command. The method allows the device processor to execute a device specific command exclusively using the write instruction of the computer's own operating system without requiring particular administrator rights.
