Abstract
The present application relates to a system hosting a monotonic counter and a method of operating the system. The system comprises a non-volatile memory () for holding a save counter value and a volatile memory () for maintaining a current counter value. The system () is configured during a startup phase to retrieve the saved counter value of the monotonic counter from the non-volatile memory (); to detect whether a previous shutdown of the system () was an uncontrolled shutdown; and to adjust the retrieved counter value in accordance with a step size () provided at the system () in case an previous uncontrolled shutdown is detected.
