Abstract

Provided is a device unit, including a module, which can configure the device unit with an operating state from among different operating states during the start-up process and/or during ongoing operation of the device unit, wherein a first protected operating state of the different operating states is designed to allow the execution of at least one operating process which can be predefined and to optionally protect the operating process by means of defined cryptographic means, wherein at least one second operating state of the different operating states is designed to deactivate the first protected operating state and to allow at least one other changeable operating process and to optionally protect the operating process by means of specifiable cryptographic means.
