DEVICE AND METHOD FOR PROVIDING AT LEAST ONE SECURE CRYPTOGRAPHIC KEY FOR CRYPTOGRAPHICALLY PROTECTING DATA INITIATED BY A CONTROL DEVICE

摘要

The invention relates to a device (SS) for providing at least one cryptographic key for a control device (FD), comprising: a configuration unit (CE, CI), and a method for providing at least one secure cryptographic key for the control unit initiated cryptographic protection of data. DB = EPODOC & ... PN = EP0284354 adapted to configure the key selectable by a purpose specification by the controller in response to an operating state (DO) of the controller and to provide the configured key to a processing unit (CPU) containing the provided key for used by the controller (cmd) cryptographic protection of data.
