Abstract: The electronic control unit includes a communication circuit adapted to receive intelligent transport system messages, an authentication circuit designed to authenticate the received messages, a non-volatile memory configured to record the authenticated received messages, and a secure element. The secure element includes a blacklist of automatically excluded senders and is configured to directly reject a received message from a sender on the blacklist without authentication using the authentication circuit. Alternatively, the secure element includes a whitelist of automatically allowed senders and is configured to directly record a received message from a sender on the whitelist in the non-volatile memory without authentication using the authentication circuit.

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

Abstract: A secure element includes a non-volatile memory. The non-volatile memory stores first instructions relating to pre-established security functions and at least one second instruction relating to at least one other personalized function. A processing unit executes at least one instruction from amongst the first instructions and the at least one second instruction obtained from the non-volatile memory.
