DEVICE AND METHOD FOR SAFELY OPERATING THE DEVICE

摘要

A device includes a controller configured to carry out a control operation using a cryptographically determined parameter, and a safety apparatus for making available the cryptographically determined parameter. The device also includes a first physical interface configured to transmit the cryptographically determined parameter from the safety apparatus to the control apparatus, an enabling apparatus for making available enabling information for enabling the safety apparatus, and a second physical interface configured to transmit the enabling information from the enabling apparatus to the safety apparatus. The safety apparatus is configured to transmit the cryptographically determined parameter to the control apparatus via the first physical interface as a function of reception of the enabling information via the second physical interface.
