Abstract
Disclosed herein is an electronic control unit including a communication circuit designed to receive intelligent transport system (ITS) messages, an authentication circuit for authenticating the received messages, and a secure element containing a hardware-secure non-volatile memory and a continually active clock counter. The secure element is configured to assign a timestamp data item from the clock counter to each of the authenticated received messages and to store the authenticated messages along with their respective timestamp data in the hardware-secure non-volatile memory.
