Abstract

A system comprises a vehicle, a broker, and a back office. The broker receives a token and a request from a requester for a mechatronics ECU in the vehicle to process a task. The back office receives the token and the request, confirms that the requester is authorized to send the request, generates a MAC for the request based on a key, creates a message protected by acknowledgment data, and transmits the request, the MAC, and the message to the broker. The broker transmits the request, the MAC, and the message to a telematics control unit in the vehicle. Based on the key shared with the back office, the telematics control unit confirms the MAC, verifies the origin of the message, and, confirming that the MAC is valid and the message originated from the back office, transmits the request to the electronic mechatronics control unit.
