Publication number: 20170150361Abstract: Embodiments of the disclosure can provide for secure communication in a vehicle network by distinguishing among communications at different layers of the vehicle network and using different security levels depending on the network layer. For example, a communication between different electronic control units (ECUs) in the same domain (e.g., two ECUs in the powertrain domain) may not need as much as security as a communication that originates from an ECU in a different domain (e.g., the chassis domain) or from a device outside the vehicle. This can allow for increased security where compromise is a greater possibility, such as when communications originate from outside the vehicle, and decreased security where comprise is a lesser possibility and performance is a greater concern, such as communications between ECUs within the vehicle and/or in the same domain.Type: ApplicationFiled: November 18, 2016Publication date: May 25, 2017Inventors: Anil PARYANI, Daniel L.
