Abstract:
A device for protecting a security module from manipulation attempts in a field device. A control device is configured to control the field device, a security module is configured to provide cryptographic key data which is to be used by the control device, and an interface device is connected to the control device. The security module is configured to allow the control device access to the cryptographic key data in the security module and to prevent access to the cryptographic key data in the event of a manipulation attempt on the field device.
