Method for managing intelligent transportation system communications and corresponding electronic control unit

Disclosed herein is an electronic control unit comprising: a communication circuit designed to receive an Intelligent Transport System (ITS) message; an authentication circuit for authenticating the received message; and a secure element including a hardware secure non-volatile memory and a continuous activation clock counter. The secure element is configured to assign an item of timestamp data from the clock counter to each of the authenticated received messages and to store the authenticated messages and their respective timestamp data together in the hardware secure non-volatile memory. 这里公开了一种电子控制单元，包括：通信电路，被设计为接收智能运输系统(ITS)消息；认证电路，用于认证接收消息；以及安全元件，包括硬件安全非易失性存储器和连续激活时钟计数器。安全元件被配置为将来自时钟计数器的时间戳数据项分配给已认证的接收消息中的每一个，并将已认证的消息及其相应的时间戳数据一起存储在硬件安全非易失性存储器中。
